Hello !
I am trying to increase the replication factor of a directory in our hadoop dfs
from 1 to 2.
I observe that some of the blocks (12 out of 400) always remain under
replicated, throwing the following message when I do an 'fsck' :
Under replicated blk_9084408236031628003. Target Replicas
is 2 but found 1 replica(s).
I thought it could be a problem with a specific data node in the cluster,
however I observe that the under replicated blocks belong to different data
nodes .
Please give me your thoughts.
Thanks.
Ilay
