[jira] Updated: (HADOOP-6196) sync(0); next() breaks SequenceFile

     [ https://issues.apache.org/jira/browse/HADOOP-6196?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jay Booth updated HADOOP-6196:
------------------------------

    Attachment: hadoop-6196-multipatch.txt

I had an idea for the issue of needing JVM restart to duplicate the bug reliably, if I define 5 test cases calling a common method in the same file, it'll launch in a new JVM each time under Ant, right?  I didn't see a way to run just 1 test under ant and the tests take all day to run on my machine, can anyone confirm?

Anyways, here's a new patch that attempts to run the test 5 times in different JVM instances.

> Currently, the end of the SequenceFile header is a sync block that isn't prefaced with SYNC_ESCAPE.  This means that sync(0) followed by next() fails.  Patch w/ test attached, bumps VERSION from 6 to 7.
