Subject [jira] [Resolved] (CASSANDRA-8320) 2.1.2: NullPointerException in SSTableWriter
Date Sat, 29 Nov 2014 07:23:12 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8320?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Marcus Eriksson resolved CASSANDRA-8320.
----------------------------------------
    Resolution: Fixed

finishAndThrow() is supposed to only be copy and pasted from finish() with added throw statements
in order to be able to test abort(), guess we could do something more fancy but imo it is
not worth spending time on
