Subject [jira] [Resolved] (CASSANDRA-2863) NPE when writing SSTable generated via repair
Date Thu, 21 Jul 2011 20:14:58 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-2863?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis resolved CASSANDRA-2863.
---------------------------------------

       Resolution: Cannot Reproduce
    Fix Version/s:     (was: 0.8.3)
         Assignee:     (was: Sylvain Lebresne)

Doesn't make any sense to me, either.  The only place close() is called is from index() [as
seen in the stacktrace here] and the only place index() is called is after prepareIndexing,
which sets iwriter to non-null:

{code}
            long estimatedRows = indexer.prepareIndexing();

            // build the index and filter
            long rows = indexer.index();
{code}

> 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.
