Feeding animals and managing their dietary needs. Replenishing fresh water throughout the day. Training animals to respond to commands. Caring for sick, injured or unhappy animals. Zookeepers work both inside and outside in all types of weather and conditions. Because animals need constant care, food and water, zookeepers might work long or unusual hours, including evenings and weekends. Zookeepers are on their feet often and might have to do physical tasks such as lifting heavy objects, moving cages and cleaning.
Being a zookeeper can be physically and emotionally demanding. Zookeepers are at risk of getting bitten, kicked or otherwise injured when handling or restraining animals.
They might have to manage stressful or difficult situations such as animals becoming injured, sick or euthanized. You do not need an advanced degree or special training to be a zookeeper. However, certain education and training steps can better prepare you for the job and make you a more desirable candidate for employers. To become a zookeeper, you might:. A high school diploma or GED is the minimum educational requirement for most zookeeper jobs.
As soon as you know you want to be a zookeeper, start getting experience handling and caring for animals. This could be while you are in high school or after graduating. Look for internships or volunteer positions at zoos, aquariums, wildlife rehabilitation centers, humane societies or other animal care facilities. Some zoos give preference to people who have interned there when hiring new zookeepers. These positions might also earn you a job reference or provide networking opportunities.
An associate degree can provide you with the experience and knowledge needed to be a zookeeper. Some community colleges partner with local zoos to provide associate degrees in subjects such as zoo technology, animal care and management, animal training and wildlife education.
You could pursue a life sciences degree such as biology or zoology, and take elective courses in topics like animal behavior. If you know you want to specialize in a certain species, such as primates, look for programs that offer courses on that subject. What does it take to become a Zoo Keeper? Find out here. There are more than zoo keepers employed at our three zoos to ensure world-class welfare and care is provided for a range of native Australian, exotic and endangered animals across the three properties.
Applying for a position as a Zoo Keeper with Zoos Victoria is slightly complex compared to other advertised roles as you must be on our Preferred Keeper List see below in order to be considered for a zoo keeping role.
Although a qualification is not required to become an entry-level zoo keeper, qualifications are looked upon favourably due to the high number of applications we receive. These institutes are. We recommend getting some work experience or either paid or volunteer experience working with animals farm animals, domestic animals, or wildlife.
If a client gets a successful return code, the update will have been applied. On some failures communication errors, timeouts, etc the client will not know if the update has applied or not. We take steps to minimize the failures, but the only guarantee is only present with successful return codes.
This is called the monotonicity condition in Paxos. Any updates that are seen by the client, through a read request or successful update, will never be rolled back when recovering from server failures. The clients view of the system is guaranteed to be up-to-date within a certain time bound. On the order of tens of seconds. Either system changes will be seen by a client within this bound, or the client will detect a service outage.
See Recipes and Solutions for more details. Sometimes developers mistakenly assume one other guarantee that ZooKeeper does not in fact make. This is:. ZooKeeper does not guarantee that at every instance in time, two different clients will have identical views of ZooKeeper data. Due to factors like network delays, one client may perform an update before another client gets notified of the change.
Consider the scenario of two clients, A and B. So, ZooKeeper by itself doesn't guarantee that changes occur synchronously across all servers, but ZooKeeper primitives can be used to construct higher level functions that provide useful client synchronization. For more information, see the ZooKeeper Recipes. The ZooKeeper client libraries come in two languages: Java and C. The following sections describe these. There are two packages that make up the ZooKeeper Java binding: org. The rest of the packages that make up ZooKeeper are used internally or are part of the server implementation.
The org. Its two constructors differ only by an optional session id and password. ZooKeeper supports session recovery accross instances of a process. A Java program may save its session id and password to stable storage, restart, and recover the session that was used by the earlier instance of the program. When a ZooKeeper object is created, two threads are created as well: an IO thread and an event thread. All event callbacks happen on the event thread.
Session maintenance such as reconnecting to ZooKeeper servers and maintaining heartbeat is done on the IO thread. Responses for synchronous methods are also processed in the IO thread. All responses to asynchronous methods and watch events are processed on the event thread. There are a few things to notice that result from this design:.
All completions for asynchronous calls and watcher callbacks will be made in order, one at a time. The caller can do any processing they wish, but no other callbacks will be processed during that time. Callbacks do not block the processing of the IO thread or the processing of the synchronous calls. Synchronous calls may not return in the correct order. Maybe not good practice, but not illegal either, and it makes for a simple example.
On a close, the two threads shut down and any further access on zookeeper handle is undefined behavior and should be avoided. The C binding has a single-threaded and multi-threaded library. The multi-threaded library is easiest to use and is most similar to the Java API. This library will create an IO thread and an event dispatch thread for handling connection maintenance and callbacks. The single-threaded library allows ZooKeeper to be used in event driven applications by exposing the event loop used in the multi-threaded library.
The former only provides the asynchronous APIs and callbacks for integrating into the application's event loop. The only reason this library exists is to support the platforms were a pthread library is not available or is unstable i.
FreeBSD 4. If you're building the client from a check-out from the Apache repository, follow the steps outlined below. If you're building from a project source package downloaded from apache, skip to step 3.
This will create a directory named "generated" under Change directory to the Make sure you have autoconf version 2. Skip to step 4. Here are some of options the configure utility supports that can be useful in this step:.
Enables optimization and enables debug info compiler options. Disabled by default. Enabled by default. Run make or make install to build the libraries and install them. All documentation will be placed in a new subfolder named docs.
By default, this command only generates HTML. For information on other document formats, run. You can test your client by running a ZooKeeper server see instructions on the project wiki page on how to run it and connecting to it using one of the cli applications that were built as part of the installation procedure. This is a client application that gives you a shell for executing simple ZooKeeper commands. Once successfully started and connected to the server it displays a shell prompt. You can now enter ZooKeeper commands.
For example, to create a node:. This section surveys all the operations a developer can perform against a ZooKeeper server. It is lower level information than the earlier concepts chapters in this manual, but higher level than the ZooKeeper API Reference.
It covers these topics:. Both the Java and C client bindings may report errors. The Java client binding does so by throwing KeeperException, calling code on the exception will return the specific error code. API callbacks indicate result code for both language bindings. See the API documentation javadoc for Java, doxygen for C for full details on the possible errors and their meaning. So now you know ZooKeeper. It's fast, simple, your application works, but wait Here are some pitfalls that ZooKeeper users fall into:.
If you are using watches, you must look for the connected watch event. When a ZooKeeper client disconnects from a server, you will not receive notification of changes until reconnected. If you are watching for a znode to come into existance, you will miss the event if the znode is created and deleted while you are disconnected. You must test ZooKeeper server failures. The ZooKeeper service can survive failures as long as a majority of servers are active.
The question to ask is: can your application handle it? In the real world a client's connection to ZooKeeper can break. ZooKeeper server failures and network partitions are common reasons for connection loss.
The ZooKeeper client library takes care of recovering your connection and letting you know what happened, but you must make sure that you recover your state and any outstanding requests that failed. Find out if you got it right in the test lab, not in production - test with a ZooKeeper service made up of a several of servers and subject them to reboots.
