Kevin Risden commented on SOLR-8538:
------------------------------------
Just want to add a note here in case anyone else stumbles across this:
The Kerberos ticket renewal issue is fixed as stated above in Hadoop 2.6.1 and
2.7.0. Solr 6.2.0 updated to Hadoop 2.7.2 dependencies. As far as I can tell,
if you are using > JDK 1.7.9_79 or JDK 1.8 then you need to use Hadoop 2.6.1+
dependencies for Solr <6.2.0 and want to store indices on Kerberized HDFS.
> Kerberos ticket is not renewed automatically when storing index on secured
> HDFS

> 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.
