[jira] [Commented] (CASSANDRA-6098) NullPointerException causing
query timeout
[ https://issues.apache.org/jira/browse/CASSANDRA-6098?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13777943#comment-13777943 ]
Lex Lythius commented on CASSANDRA-6098:
----------------------------------------
This happens only when querying for some particular values on a secondary index. Cannot reproduce it querying by primary key.
Neither of the following did any good:
{noformat}
restarting cassandra
nodetool invalidaterowcache
nodetool invalidatekeycache
nodetool cleanup
nodetool repair
{noformat}
