Re: Measuer Bytes READ and Peak Memory Usage for Query
Yeah thanks, I can now see the memory usage. Please also verify if bytes read == Combined size of all RDDs ? Actually, all my RDDs are completely cached in memory. So, Combined size of my RDDs = Mem used (verified from WebUI) On Fri, Mar 20, 2015 at 12:07 PM, Akhil Das ak...@sigmoidanalytics.com wrote: You could do a cache and see the memory usage under Storage tab in the driver UI (runs on port 4040) Thanks Best Regards On Fri, Mar 20, 2015 at 12:02 PM, anu anamika.guo...@gmail.com wrote: Hi All I would like to measure Bytes Read and Peak Memory Usage for a Spark SQL Query.
