Ryan Hesson commented on SOLR-6775:
-----------------------------------
Sure, I really appreciate the help. Please let me know if I can share any more
information.
Thank you for your time,
Ryan
This is my setting on the master Solr index:
<requestHandler name="/replication" class="solr.ReplicationHandler" >
<lst name="master">
<str name="replicateAfter">commit</str>
<str name="replicateAfter">startup</str>
<str name="backupAfter">optimize</str>
<str name="confFiles">schema.xml,stopwords.txt</str>
</lst>
<int name="maxNumberOfBackups">2</int>
</requestHandler>
This is my setting on the slave Solr index:
<requestHandler name="/replication" class="solr.ReplicationHandler" >
<lst name="slave">
<str name="masterUrl">[Server URL]:8983/solr/[Core Name]</str>
<str name="pollInterval">01:00:00</str>
</lst>
</requestHandler>
Far as API call, I know I'm doing add/update documents to the core and then a
commit. Here's additional log info if it helps:

> Creating backup snapshot null pointer exception
> -----------------------------------------------
>
> Key: SOLR-6775
> URL: https://issues.apache.org/jira/browse/SOLR-6775
> Project: Solr
> Issue Type: Bug
> Components: replication (java)
> Affects Versions: 4.10
> Environment: Linux Server, Java version "1.7.0_21", Solr version
> 4.10.0
> Reporter: Ryan Hesson
> Labels: snapshot, solr
>
> I set up Solr Replication. I have one master on a server, one slave on
> another server. The replication of data appears functioning correctly. The
> issue is when the master SOLR tries to create a snapshot backup it gets a
> null pointer exception.
> org.apache.solr.handler.SnapShooter createSnapshot method calls
> org.apache.solr.handler.SnapPuller.delTree(snapShotDir); at line 162 and the
> exception happens within org.apache.solr.handler.SnapPuller at line 1026
> because snapShotDir is null.
> Here is the actual log output:
> 58319963 [qtp12610551-16] INFO org.apache.solr.core.SolrCore - newest
> commit generation = 349
> 58319983 [Thread-19] INFO org.apache.solr.handler.SnapShooter - Creating
> backup snapshot...
> Exception in thread "Thread-19" java.lang.NullPointerException
> at org.apache.solr.handler.SnapPuller.delTree(SnapPuller.java:1026)
> at
> org.apache.solr.handler.SnapShooter.createSnapshot(SnapShooter.java:162)
> at org.apache.solr.handler.SnapShooter$1.run(SnapShooter.java:91)
> I may have missed how to set the directory in the documentation but I've
> looked around without much luck. I thought the process was to use the same
> directory as the index data for the snapshots. Is this a known issue with
> this release or am I missing how to set the value? If someone could tell me
> how to set snapshotdir or confirm that it is an issue and a different way of
> backing up the index is needed it would be much appreciated.
