Subject getting HDFS to rack-aware mode
Date Tue, 14 Oct 2008 19:06:40 GMT

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"?
