Subject [jira] [Commented] (CASSANDRA-2863) NPE when writing SSTable generated via repair
Date Fri, 23 Sep 2011 15:18:26 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13113501#comment-13113501

chris erway commented on CASSANDRA-2863:
----------------------------------------

Since my last two comments, I increased my RF and started a rolling repair on my nodes.  This
has caused this NPE to pop up on all the boxes as the process SSTables.  Again, all the nodes
are fresh 0.8.6 installs from a few days ago using the ComboAMI.

> A NPE is generated during repair when closing an sstable generated via SSTable build.
It doesn't happen always. The node had been scrubbed and compacted before calling repair.
