Eli Collins resolved HDFS-276.
------------------------------
Resolution: Duplicate
dupe of HDFS-903
> Checksums for Namenode image files
> ----------------------------------
>
> Key: HDFS-276
> URL: https://issues.apache.org/jira/browse/HDFS-276
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Raghu Angadi
>
> Currently DFS can write multiple copies of image files but we do not
> automatically recover from corrupted or truncated image files well. This jira
> intends to keep CRC for image file records and Namenode should recover
> accurate image as long as data exists in one of the copies (e.g. it should be
> ok to have non overlapping corruptions in the copies). Will add more details
> in next comment.
