> Key: ACCUMULO-3596
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3596
> Project: Accumulo
> Issue Type: Bug
> Components: master, tserver
> Environment: large cluster
> Reporter: Eric Newton
> Assignee: Eric Newton
>
> calls to importDirectory were hanging. After some debugging, it was determined that the imports were stuck waiting on DNS lookups.
> {{InetAddress#getByName}} calls {{gethostbyname_r}}
> Further, it was determined that the call only hangs if /etc/hosts.conf contains "reorder on".
> A bug was found in this section of the glibc resolver, and a bug report will be made to them.
> Workaround: turn off address reordering.
> Many thanks to [~bfloss] for finding this bug.
