When starting hadoop, it stays in safe mode forever. Looking into the issue, seems there is problem with block replication.
Command hadoop fsck / shows error msg: /XXXXX/part-00007.deflate: CORRUPT block blk_1402039344260425079 /XXXXX/part-00007.deflate: MISSING 1 blocks of total size 2294 B...................... Tried to restart the fs , it doesn't solve the problem. Question: how to find the data node that contains corrupted/missing blocks? Thanks, Joey
