Subject [jira] [Commented] (CASSANDRA-5599) Intermittently, CQL SELECT with WHERE on secondary indexed field value returns null when there are rows
Date Thu, 06 Jun 2013 09:01:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13676854#comment-13676854

Michał Michalski commented on CASSANDRA-5599:
---------------------------------------------

To make sure: does it work after recreating index or the problem still happens sometimes?
If it's still failing sometimes:
* Did you try running repair?
* What consistency level do you use for writes and reads?
* How many nodes do you have? 
* Does it happen when you SELECT with CL.CL.ALL?

> Intermittently, CQL SELECT  with WHERE on secondary indexed field value returns null
when there are rows.
> As it happens intermittently, it is difficult to replicate. To resolve we have had to
recreate the index. Also using the nodetool to reindex did not help us either.
> We would create a table, create a secondary index for that table on a field, import data
then when we try to select rows from that table with where on said field which should return
results, we get a null back ...intermittently.  Sometimes works, sometimes not.
