------------------------------------
Summary: Sudden Death of master, gc, and tservers
Key: ACCUMULO-1374
URL: https://issues.apache.org/jira/browse/ACCUMULO-1374
Project: Accumulo
Issue Type: Bug
Components: gc, master, tserver
Environment: 1.5, svn#1470047 & 1477382 - both in standalone instance
on ec2 on ubuntu and small cluster on bare metal CentOs
Reporter: John Vines
Assignee: Eric Newton
Priority: Blocker
Fix For: 1.5.0
I wish I could provide more information. This has happened once on a bare metal
centos cluster while running vanilla continuous ingest of svn#1470047. There
was nothing reported in the logs when one of the tservers just died after the
system had been up for ~1 day. The out and err files were sparse, and the
master only reported that it had lost connection with the tserver at the point
when the tserver just stopped logging (it was overnight, so this was not
witnessed until morning).
It recently happened again on a standalone instance on ec2 running ubuntu and
svn#1477382. The instance had been running for ~7 hours. This time the gc,
master, and tserver died. The gc died first, and then 2m:48s later the master
died. 200ms later the tserver died. Again, there was no output in any of the
out or err files for the processes. The logs also have no errors or warnings in
them, just abrupt stops. The processes came up fine once restarted.
