Subject [jira] Commented: (HDFS-706) Intermittent failures in TestFiHFlush
Date Wed, 28 Oct 2009 17:39:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12771013#action_12771013
] 

Konstantin Boudnik commented on HDFS-706:
-----------------------------------------

I assume you see this one as a result of 
{noformat}
org.apache.hadoop.util.DiskChecker$DiskErrorException: FI: DerrAction:hFlushFi02_c, index=1,
datanode=
{noformat}
If so - yes it is there and it is reproducible. It seems to be a result of {{DiskErrorException}}
on a second DN when the write happens across block and checksum boundaries. I've no idea why
it happens only in this case, but it seems to be Ok for the test is getting the expecting
behavior, e.g. the exception goes through.
