Subject Verifying the distribution of data across region servers - hotspotting
Date Thu, 15 Oct 2015 21:51:34 GMT

I'm afraid that my cluster is suffering of a bit of hotspotting, what's the
best way to verify that?

Is it enough to verify the data size handled by each regionserver with the
hdfs dfs -du command? Is there a way to easily count the number of records
handled by each regionserver? How about the number of read/writes handled
by each of them?
