[jira] [Issue Comment Edited] (CASSANDRA-2863) NPE when writing
SSTable generated via repair
[ https://issues.apache.org/jira/browse/CASSANDRA-2863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13109079#comment-13109079 ]

I just got a similar-looking NPE stack trace. The node that raised the exception was receiving streams from a node being decommissioned (with "nodetool decommission"). Both nodes were running 0.8.6; both had been upgraded a few hours earlier from 0.8.4.
The first:

> Issue Type: Bug
> Components: Core
> Affects Versions: 0.8.1
> Reporter: Héctor Izquierdo
>
> 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.
