The excerpt from your log that I preserved above shows that the root of
the problem is something going wrong with Solr writing to HDFS.  I can
only tell that there was a problem, I do not what actually went wrong.

I think you'll need to take this information to the hadoop project and
ask them what could cause it and what can be done about it.

Solr includes Hadoop 2.7.2 jars.  This is not the latest version of
Hadoop, so it's possible there might be a known issue with this version
that is fixed in a later version.  There is a task to update Solr's
Hadoop to 3.0 when it gets released:
