WebHCat
ZooKeeper Usage:
/templeton-hadoop
- WebHCat stores status of jobs that users can query in zookeeper (if ZooKeeperStorage is configured to find out the status of jobs - it can also use HDFS for this storage). WebHCat typically will create three znodes inside this root : “jobs”, “overhead” and “created”. This root node is exposed via config :templeton.storage.root
. In addition, whether or not ZooKeeperStorage is used is configured by another config parameter :templeton.storage.class
. Both these parameters are part ofwebhcat-site.xml
. These nodes are altered from launcher map task as well, which runs as the end user.
