Mingliang Liu created HDFS-9867: ----------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
