Subject [jira] [Updated] (HDFS-2797) Fix misuses of InputStream#skip in the edit log code
Date Mon, 04 Jun 2012 18:58:27 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2797?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Colin Patrick McCabe updated HDFS-2797:
---------------------------------------

    Description: 
Fix some misuses of InputStream#skip in the edit log code.

Also add a test.  The existing failover tests only cover the case of graceful shutdown. We
should make sure the standby NN can become active even when the final transaction in an edit
log is only partially written to disk.

  was:The existing failover tests only cover the case of graceful shutdown. We should make

     Issue Type: Bug  (was: Test)
        Summary: Fix misuses of InputStream#skip in the edit log code  (was: HA: Add a test
