---------------------------------
Summary: HMaster does not go down while splitting logs even if
explicit shutdown is called.
Key: HBASE-6293
URL: https://issues.apache.org/jira/browse/HBASE-6293
Project: HBase
Issue Type: Bug
Affects Versions: 0.94.0, 0.92.1
Reporter: rajeshbabu
Assignee: rajeshbabu
Fix For: 0.92.2, 0.96.0, 0.94.1
When master starts up and tries to do splitlog, in case of any error we try to
do that infinitely in a loop until it succeeds.
But now if we get a shutdown call, inside SplitLogManager
{code}
if (stopper.isStopped()) {
LOG.warn("Stopped while waiting for log splits to be completed");
return;
}
{code}
Here we know that the master has stopped. As the task may not be completed now
{code}
if (batch.done != batch.installed) {
batch.isDead = true;
tot_mgr_log_split_batch_err.incrementAndGet();
LOG.warn("error while splitting logs in " + logDirs +
" installed = " + batch.installed + " but only " + batch.done + " done");
throw new IOException("error or interrupt while splitting logs in "
+ logDirs + " Task = " + batch);
}
{code}
we throw an exception. In MasterFileSystem.splitLogAfterStartup() we don't
check if the master is stopped and we try continously.
