Subject Re: Both hadoop fsck and dfsadmin can not detect missing replica in time?
Date Fri, 14 Nov 2014 15:06:12 GMT
Hi,

When hadoop finds a missing replica of a block it will replicate that block
in some other node (it need at least 1 good block to replicate that you
have it in data node 1).  So you can not see that in fsck.  If you want to
test that, fsck should let you know the missing replica. Delete from both
datanode block. That time you will see it in fsck.

Thanks
Abirami
