Method Detail

getPool

private ExecutorService getPool()

Returns:

a pool that has one thread only at every time. A second action added to the pool ( running concurrently), will cause an exception.

getRegionObserver

public Optional<org.apache.hadoop.hbase.coprocessor.RegionObserver> getRegionObserver()

Specified by:

getRegionObserver in interface org.apache.hadoop.hbase.coprocessor.RegionCoprocessor

prePut

public void prePut(org.apache.hadoop.hbase.coprocessor.ObserverContext<org.apache.hadoop.hbase.coprocessor.RegionCoprocessorEnvironment> e,
                   org.apache.hadoop.hbase.client.Put put,
                   org.apache.hadoop.hbase.wal.WALEdit edit,
                   org.apache.hadoop.hbase.client.Durability durability)
            throws IOException

Specified by:

prePut in interface org.apache.hadoop.hbase.coprocessor.RegionObserver

Throws:

IOException
