Examples with ExecutorStatusChore org.apache.hadoop.hbase.ExecutorStatusChore used on opensource projects

Example 1 with ExecutorStatusChore

use of org.apache.hadoop.hbase.ExecutorStatusChore in project hbase by apache.

the class HRegionServer method startServices.

/**
 * Start maintenance Threads, Server, Worker and lease checker threads.
 * Start all threads we need to run. This is called after we've successfully
 * registered with the Master.
 * Install an UncaughtExceptionHandler that calls abort of RegionServer if we
 * get an unhandled exception. We cannot set the handler on all threads.
 * Server's internal Listener thread is off limits. For Server, if an OOME, it
 * waits a while then retries. Meantime, a flush or a compaction that tries to
 * run should trigger same critical condition and the shutdown will run. On
 * its way out, this server will shut down Server. Leases are sort of
 * inbetween. It has an internal thread that while it inherits from Chore, it
 * keeps its own internal stop mechanism so needs to be stopped by this
 * hosting server. Worker logs the exception and exits.
