-----------------------------------
Summary: 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: 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.
