Subject [jira] [Commented] (CASSANDRA-5761) Issue with secondary index sstable.
Date Wed, 17 Jul 2013 17:51:59 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5761?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13711352#comment-13711352
] 

Jonathan Ellis commented on CASSANDRA-5761:
-------------------------------------------

You would get that error if you are inserting empty partition keys, but we guard against that.
 Are you bypassing validation somehow, e.g. with json2sstable or by direct calls to StorageProxy?

> With Cassandra 1.2.5 having issue very similar to [CASSANDRA-5225|https://issues.apache.org/jira/browse/CASSANDRA-5225]
but for secondary index sstable. Every query that uses this index fails in Hector with ConnectionTimeout
but cassandra log says that reason is:
