Andrew Bumstead resolved SOLR-8538.
-----------------------------------
Resolution: Not A Problem
It turns out this is an effect of HADOOP-10786, which impacted automatic
re-login on certain versions of JDK. This has been fixed as of Hadoop 2.6.1,
2.7.0.
A work around for those affected is to run Solr with JDK 1.7.0_79.

> Key: SOLR-8538
> URL: https://issues.apache.org/jira/browse/SOLR-8538
> Project: Solr
> Issue Type: Bug
> Components: Hadoop Integration, hdfs, security
> Affects Versions: 5.2.1
> Environment: HDP 2.3
> Reporter: Andrew Bumstead
>
> It seems that when Solr is configured to stores its index files on a
> Kerberized HDFS, there is no built in mechanism by which Solr will renew its
> Kerberos ticket before it expires.
> The impact is that after the default ticket lifetime has elapsed (typically
> 24 hours) Solr becomes unable to connect to HDFS to read/write and requires a
> restart or a manual kinit command to be run.
