---------------------------------
Summary: 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
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.
