pavan patel created SOLR-5849:
---------------------------------
Summary: write.lock is not removed by LogReplayer
Key: SOLR-5849
URL: https://issues.apache.org/jira/browse/SOLR-5849
Project: Solr
Issue Type: Bug
Environment: Windows 7, Tomcat 7.0.52, Solr 4.3.0, jdk1.7.0_51
Reporter: pavan patel
I my application I am using SolrEmbeddedServer inside tomcat. I have below
configuration for my core:-
<lockType>simple</lockType>
<unlockOnStartup>true</unlockOnStartup>
<updateLog>
<str name="dir">${solr.ulog.dir:}</str>
</updateLog>
<autoCommit>
<maxTime>15000</maxTime>
<openSearcher>false</openSearcher>
</autoCommit>
<autoSoftCommit>
<maxTime>1000</maxTime>
</autoSoftCommit>
The issue I am facing is when I restart tocmat and in case there is any
uncommitted data in tlog, then I am getting below exception:-
org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out:

After restart I am not able to index anything into the solr. I debug the code
and found out that LogReplayer during start up creates the SolrIndexWriter on
core and that creates the write.lock file. Once all the leftover tlog's are
indexed, the write.lock remains there, its not getting deleted. So when my
application tries to add document the SolrIndexWriter is not able to create the
lock because write.lock already exists.
This seems to be a bug in Solr 4.3.0, because I believe SolrIndexWriter created
during LogReplayer is not closed that causing the write.lock leftover in data
directory.
