If you see it in 1.8 or 1.9, please feel free to open a GitHub issue. > Master hangs if shutdown requested while in state "HAS_LOCK" > ------------------------------------------------------------ > > Key: ACCUMULO-4513 > URL: https://issues.apache.org/jira/browse/ACCUMULO-4513 > Project: Accumulo > Issue Type: Bug > Affects Versions: 1.6.6, 1.7.2 > Reporter: John Vines > Priority: Critical > > The StatusThread.run() method does not have any means to change the masters > state out of HAS_LOCK when CLEAN_STOP is requested, which can cause the > master to get perpetually stuck > Additionally, because the master never hit the NORMAL state, the main > Master.run() was jammed at waitForMetadataUpgrade.await() so the thrift > server was never started and shutdown couldn't be issued directly (not > entirely confident that would have actually fixed anything though this is > contrary to the the state transition chart which says we can go from > HAVE_LOCK->STOP) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
