Description

InactiveTotalTime and TotalTime show up in the thrift profiles but aren't explicitly shown in the Impala pretty-printed text profile.

TotalTime and InactiveTotalTime are handled specially - they are factored into the timings printed in the header of each profile section, e.g HDFS_SCAN_NODE (id=5):(Total: 10.213ms, non-child: 10.213ms, % non-child: 100.00%). InactiveTotalTime is non-zero only for exchange nodes.

Impala does a calculation involving those two counters: https://github.com/apache/incubator-impala/blob/7866eec5bdcbf9194a4aad2c87c354cbaad7b802/be/src/util/runtime-profile.cc#L362 then prints the result in the text profile: https://github.com/apache/incubator-impala/blob/7866eec5bdcbf9194a4aad2c87c354cbaad7b802/be/src/util/runtime-profile.cc#L625

We should include/exclude things from the thrift profile that prevent consumers of the thrift profile from presenting identical information to the pretty-printed text profiles.
