Subject [jira] [Updated] (HDFS-9867) Missing block exception should carry locatedBlocks information
Date Sat, 27 Feb 2016 04:08:18 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9867?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
