Konstantin Boudnik commented on HDFS-1222:
------------------------------------------
hasn't it been addressed by recent work in HDFS-903 and such? If so, let's
close this as dup then.
> NameNode fail stop in spite of multiple metadata directories
> ------------------------------------------------------------
>
> Key: HDFS-1222
> URL: https://issues.apache.org/jira/browse/HDFS-1222
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: name-node
> Affects Versions: 0.20.1
> Reporter: Thanh Do
>
> Despite the ability to configure multiple name directories
> (to store fsimage) and edits directories, the NameNode will fail stop
> in most of the time it faces exception when accessing to these directories.
>
> NameNode fail stops if an exception happens when loading fsimage,
> reading fstime, loading edits log, writing fsimage.ckpt ..., although there
> are still good replicas. NameNode could have tried to work with other
> replicas,
> and marked the faulty one.
> This bug was found by our Failure Testing Service framework:
> http://www.eecs.berkeley.edu/Pubs/TechRpts/2010/EECS-2010-98.html
> For questions, please email us: Thanh Do ([email protected]) and
