Jean-Daniel Cryans commented on HBASE-6550:
-------------------------------------------
Also we need to call sharedThreadPool.shutdown() before calling
awaitTermination in here:
{code}
try {
if (!sharedThreadPool.awaitTermination(60000, TimeUnit.MILLISECONDS)) {
sharedThreadPool.shutdownNow();
}
} catch (InterruptedException e) {
LOG.warn("Interrupted while closing the table pool", e); // ignoring it
as we are closing.
Thread.currentThread().interrupt();
}
{code}
awaitTermination called like this is basically delaying the shutdown of the
region server by 1 minute.

> 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 (may be due to region splitting, gc pause, etc) and it undergoes the
> retrial phase.
> It has two repercussions:
> a) The regionserver handler which is serving the request (till now, a
> priority handler) 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.
> Refactoring ReplicationSink to have the following features:
> a) Making it more configurable (have its own number of retrial limit,
> connection timeout, etc)
> b) Add a fail fast behavior so that it bails out in case caller is timedout,
> or any exception in processing the mutation batch.
