------------------------------------

             Summary: Provide admin/debug tool to dump out info of a given block
                 Key: HDFS-10919
                 URL: https://issues.apache.org/jira/browse/HDFS-10919
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: hdfs
            Reporter: Yongjun Zhang


We have fsck to find out blocks associated with a file, which is nice. Sometimes, we saw trouble with a specific block, we'd like to collect info about this block, such as
* what file this block belong to, 
* where the replicas of this block are located, 
* whether the block is EC coded; 
* if a block is EC coded, whether it's a data block, or code
* if a block is EC coded, what's the codec.
* if a block is EC coded, what's the block group
* for the block group, what are the other blocks

Create this jira to provide such a util, as dfsadmin, or a debug tool.

Thanks.
