Description
ReplicationSink replicates the WALEdits in the local cluster. It uses native HBase client to insert the mutations. Sometime, it takes a while to process it (region splitting, gc pause, etc) and it undergoes the retrial phase. It has two repercussions:
a) The regionserver handler which is serving the request is blocked for this period.
b) The caller may get timed out and it will retry it anyway, but the handler serving the ReplicationSink requests is still working.
