shutdown is very slow after all tservers are down
-------------------------------------------------
Key: ACCUMULO-236
URL: https://issues.apache.org/jira/browse/ACCUMULO-236
Project: Accumulo
Issue Type: Bug
Components: master
Affects Versions: 1.3.5
Environment: on a larger cluster shutdown takes a long time
Reporter: Eric Newton
Assignee: Eric Newton
After all tablets are unloaded (as reported in the monitor web pages) and all
tablet servers appear to be down, the shutdown command hangs. The master log
messages show something like
{{{
... Unable to halt server 10.1.2.3:9997[abc123456789]:
org.apache.thrift.transport.TTransportException
}}}
One error for every server, making this problem much worse on a large cluster.
Thought we fixed this for 1.3.5, but it was reported again after the release.
