-------------------------------
Resolution: Duplicate
Why file this bug if it's the same as 955?
> Data Loss due to edits log truncation
> -------------------------------------
>
> Key: HDFS-1219
> URL: https://issues.apache.org/jira/browse/HDFS-1219
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: name-node
> Affects Versions: 0.20.2
> Reporter: Thanh Do
>
> We found this problem almost at the same time as HDFS developers.
> Basically, the edits log is truncated before fsimage.ckpt is renamed to
> fsimage.
> Hence, any crash happens after the truncation but before the renaming will
> lead
> to a data loss. Detailed description can be found here:
> https://issues.apache.org/jira/browse/HDFS-955
> 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 (than...@cs.wisc.edu) and
