Subject [jira] [Updated] (CASSANDRA-4975) AE in Bounds when running word count
Date Mon, 26 Nov 2012 18:24:58 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-4975?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Brandon Williams updated CASSANDRA-4975:
----------------------------------------

    Attachment: 4975.txt

WordCount has is using RP, causing invalid bounds for M3P.  Something seems too fragile here
since the job hangs forever after the AE, but for rc1 let's just change the partitioner to
M3P.  Patch to do so.
