Mingliang Liu updated HDFS-9867:
--------------------------------
Component/s: erasure-coding
> Missing block exception should carry locatedBlocks information
> --------------------------------------------------------------
>
> Key: HDFS-9867
> URL: https://issues.apache.org/jira/browse/HDFS-9867
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: erasure-coding, hdfs-client
> Reporter: Mingliang Liu
> Assignee: Mingliang Liu
> Priority: Minor
>
> When more than {{parityBlkNum}} internal blocks are missing, {{StripeReader}}
> throws IOException. Sample error message like:
> {quote}
> java.io.IOException: 5 missing blocks, the stripe is: Offset=44695552,
> length=65536, fetchedChunksNum=0, missingChunksNum=5
> {quote}
> According to our recent experience, it'd be useful for debugging and
> diagnosing to dump the current block group information.
