Raghu Angadi commented on HDFS-729:
-----------------------------------
As I understand, list of files returned in one call will not have duplicates.
500 is a lot.. note that these are files with 'hard-corruption', ie, HDFS could
not repair them. Once a cluster has so many corrupt files, I would think there
would be a lot more urgent things to worry about than finding rest of the
corrupt files. In practice, most likely reason for such a scenario would be a
large number of datanodes go missing.
> fsck option to list only corrupted files
