Examples of org.apache.hadoop.hbase.Abortable

org.apache.hadoop.hbase.Abortable
Interface to support the aborting of a given server or client.
This is used primarily for ZooKeeper usage when we could get an unexpected and fatal exception, requiring an abort.
Implemented by the Master, RegionServer, and TableServers (client).
