stack commented on HBASE-8939:
------------------------------
Am going to disable TestLogRollAbort. Will open new issue to have it looked
at. It is a test to ensure no dataloss around deferred sync. Deferred sync
has changed a bunch since this test was originally written. Interesting is
this bit in the test:
{code}
// set periodic sync to 2 min so it doesn't run during test
TEST_UTIL.getConfiguration().setInt("hbase.regionserver.optionallogflushinterval",
120 * 1000);
{code}
But then over in FSHLog, we are doing this:
{code}
logSyncer.close();
// Make sure we synced everything
logSyncer.join(this.optionalFlushInterval * 2);
} catch (InterruptedException e) {
{code}
... before we will close so the regionserver is staying up and won't go down
when mini cluster joins on the end. There are issues w/ the JVMClusterUtil
which I'll fix in another issue.
