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.
