Worklog Id: (was: 675606)
Time Spent: 5h 40m (was: 5.5h)
> Debug tool to verify the correctness of erasure coding on file
> --------------------------------------------------------------
>
> Key: HDFS-16286
> URL: https://issues.apache.org/jira/browse/HDFS-16286
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: erasure-coding, tools
> Affects Versions: 3.3.0, 3.3.1
> Reporter: daimin
> Assignee: daimin
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.4.0, 3.2.3, 3.3.2
>
> Time Spent: 5h 40m
> Remaining Estimate: 0h
>
> Block data in erasure coded block group may corrupt and the block meta
> (checksum) is unable to discover the corruption in some cases such as EC
> reconstruction, related issues are: HDFS-14768, HDFS-15186, HDFS-15240.
> In addition to HDFS-15759, there needs a tool to check erasure coded file
> whether any block group has data corruption in case of other conditions
> rather than EC reconstruction, or the feature HDFS-15759(validation during EC
> reconstruction) is not open(which is close by default now).
