ClassDescriptionTracker on cluster settings up in zookeeper.A ZooKeeper watcher meant to detect deletions of ZNodes.An empty ZooKeeper watcherHBase's version of ZooKeeper's QuorumPeer.Placeholder of an instance which will be accessed by other threads but is not yet created.Manages the location of the current active Master for the RegionServer.Tracks the master Maintenance Mode via ZK.Utility class to perform operation (get/wait for/verify/set/delete) on znode in ZooKeeper which keeps hbase:meta region server location.Interface of the source that will export metrics about the ZooKeeper.Class that transitions metrics from MetricsZooKeeper into the metrics subsystem.TODO: Most of the code in this class is ripped from ZooKeeper tests.Placeholder of a watcher which might be triggered before the instance is not yet created.A very simple read only zookeeper implementation without watcher support.A zookeeper that can handle 'recoverable' errors.You may add the jaas.conf option -Djava.security.auth.login.config=/PATH/jaas.conf You may also specify -D to set options "hbase.zookeeper.quorum" (it should be in hbase-site.xml) "zookeeper.znode.parent" (it should be in hbase-site.xml) Use -set-acls to set the ACLs, no option to erase ACLsProvides ZooKeeper authentication services for both client and server processes.A JAAS configuration that defines the login modules that we want to use for ZooKeeper login.Publishes and synchronizes a unique identifier specific to a given HBase cluster.Utility methods for reading, and building the ZooKeeper configuration.Builds a string containing everything in ZooKeeper.Deprecated.Not usedBase class for internal listeners of ZooKeeper events.Tool for running ZookeeperMain from HBase by reading a ZooKeeper server from HBase XML configuration.ZooKeeper 3.4.6 broke being able to pass commands on command line.The metadata append to the start of data on zookeeper.Tracks the availability and value of a single ZooKeeper node.Tool for reading ZooKeeper servers from HBase XML configuration and producing a line-by-line list for use by bash scripts.Deprecated.since 2.4.0 and 3.0.0 replaced by procedure-based WAL splitting; see SplitWALManager.Internal HBase utility class for ZooKeeper.Deprecated.UnusedRepresents an action taken by ZKUtil, e.g.ZKUtilOp representing createAndFailSilent in ZooKeeper (attempt to create node, ignore error if already exists)ZKUtilOp representing deleteNodeFailSilent in ZooKeeper (attempt to delete node, ignore error if node doesn't exist)ZKUtilOp representing setData in ZooKeeperActs as the single ZooKeeper Watcher.Class that hold all the paths of znode for HBase.Methods that help working with ZooKeeper
