MasterFileSystem.splitLog() should abort even if waitOnSafeMode() throws
IOException
------------------------------------------------------------------------------------
Key: HBASE-5137
URL: https://issues.apache.org/jira/browse/HBASE-5137
Project: HBase
Issue Type: Bug
Affects Versions: 0.90.4
Reporter: ramkrishna.s.vasudevan
Assignee: ramkrishna.s.vasudevan
I am not sure if this bug was already raised in JIRA.
In our test cluster we had a scenario where the RS had gone down and
ServerShutDownHandler started with splitLog.
But as the HDFS was down the check waitOnSafeMode throws IOException.
{code}
try {
// If FS is in safe mode, just wait till out of it.
FSUtils.waitOnSafeMode(conf,
conf.getInt(HConstants.THREAD_WAKE_FREQUENCY, 1000));
splitter.splitLog();
} catch (OrphanHLogAfterSplitException e) {
{code}
We catch the exception
{code}
} catch (IOException e) {
checkFileSystem();
LOG.error("Failed splitting " + logDir.toString(), e);
}
{code}
So the HLog split itself did not happen. We encontered like 4 regions that was
recently splitted in the crashed RS was lost.
Can we abort the Master in such scenarios? Pls suggest.
