Class DistributedHBaseCluster

java.lang.Object
org.apache.hadoop.hbase.HBaseClusterInterface
org.apache.hadoop.hbase.DistributedHBaseCluster
All Implemented Interfaces:
Closeable, AutoCloseable, org.apache.hadoop.conf.Configurable
@Private public class DistributedHBaseCluster extends HBaseClusterInterface
Manages the interactions with an already deployed distributed cluster (as opposed to a pseudo-distributed, or mini/local cluster). This is used by integration and system tests.

    boolean
    isKilledRS(org.apache.hadoop.hbase.ServerName serverName)
    Keeping track of killed servers and being able to check if a particular server was killed makes it possible to do fault tolerance testing for dead servers in a deterministic way.
    void
    killDataNode(org.apache.hadoop.hbase.ServerName serverName)
    Kills the datanode process if this is a distributed cluster, otherwise, this causes master to exit doing basic clean up only.
    void
    killJournalNode(org.apache.hadoop.hbase.ServerName serverName)
    Kills the journalnode process if this is a distributed cluster, otherwise, this causes master to exit doing basic clean up only.
    void
    killMaster(org.apache.hadoop.hbase.ServerName serverName)
    Kills the master process if this is a distributed cluster, otherwise, this causes master to exit doing basic clean up only.
    void
    killNameNode(org.apache.hadoop.hbase.ServerName serverName)
    Kills the namenode process if this is a distributed cluster, otherwise, this causes master to exit doing basic clean up only.
    void
    killRegionServer(org.apache.hadoop.hbase.ServerName serverName)
    Kills the region server process if this is a distributed cluster, otherwise this causes the region server to exit doing basic clean up only.
    void
    killZkNode(org.apache.hadoop.hbase.ServerName serverName)
    Kills the zookeeper node process if this is a distributed cluster, otherwise, this causes master to exit doing basic clean up only.
