Raghu Angadi reassigned HADOOP-820:
-----------------------------------
Assignee: Raghu Angadi (was: Sameer Paranjpye)
> NameNode startup fails if edit log terminates
prematurely
>
---------------------------------------------------------
>
> Key: HADOOP-820
> URL: http
s://issues.apache.org/jira/browse/HADOOP-820
> Project: Hadoop
> Issue Type: Bug
> Components: dfs
> Environment: ~50 node cluster
> Reporter: Bryan Pendleton
> Assignee: Raghu Angadi
> Attachments: fixNameNodeStartup.patch
>
>
> I ran out of space on the device that stores the edit
log, resulting in an edit log that is truncated mid
transaction.
> Ideally, the NameNode should start up, in SafeMode or
the like, whenever this happens. Right now, you get this
stack trace:
