> Key: ACCUMULO-4317
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4317
> Project: Accumulo
> Issue Type: Bug
> Components: client
> Affects Versions: 1.6.5, 1.7.0, 1.7.1
> Reporter: Michiel Vanderlee
> Assignee: Michiel Vanderlee
> Priority: Blocker
> Fix For: 1.6.6, 1.7.2, 1.8.0
>
> Attachments: Accumulo-4317.patch
>
>
> Accumulo stores hostnames in zookeeper, if the client can not resolve these
> then it will continue to try to connect in a while(true) loop. This will
> eventually cause 'too many files open' errors.
> Loop is in ServerClient.java$executeRaw
> Bug: Should error out after some time, not retry infintely.
> Workaround: Add hostnames to /etc/hosts and restart.
