hi Sriram
Run hadoop fsck / will give you summary of current HDFS status including
some useful information :
Minimally replicated blocks: 51224 (100.0 %)
Over-replicated blocks: 0 (0.0 %)
Under-replicated blocks: 0 (0.0 %)
Mis-replicated blocks: 7 (0.013665469 %)
Default replication factor: 3
Average block replication: 3.0
Missing replicas: 0 (0.0 %)
Number of data-nodes: 83
Number of racks: 6
Hi,
We have a cluster where we running HDFS in non-rack-aware mode. Now,
we want to switch HDFS to run in rack-aware mode. Apart from the
config changes (and restarting HDFS), to rackify the existing data, we
were thinking of increasing/decreasing replication level a few times
to get the data spread. Are there any tools that will enable us to
know when we are "done"?
