Hi Amol, Thanks for the reply.
I restarted my apex application after 3 days of failure of old app.Till now I have not performed benchmarking of my operators/app. Still problem is persisting after 5days from restart. I manually killed application and wanted to give new configuration to old app by increasing the partitions for all the operators, but new configuration it is not taking. Looks like I have to manually kill the application and start a new application which will start writing data from today. Remaining difference of data I will have to manually load. Please suggest if there is any option in apex to get rid of latency so that I can have updated data writing on HDFS ,instead of manually loading the data.
