Subject Measuer Bytes READ and Peak Memory Usage for Query
Date Fri, 20 Mar 2015 06:32:31 GMT
Hi All

I would like to measure Bytes Read and Peak Memory Usage for a Spark SQL

Please clarify if Bytes Read = aggregate size of all RDDs ??
All my RDDs are in memory and 0B spill to disk.

And I am clueless how to measure Peak Memory Usage.
