> Setting the format is already supported Impala's HS2 interface:
> https://github.com/apache/impala/blob/45051a27672c3a8a5be304ab2c71fc5c02946788/common/thrift/ImpalaService.thrift#L1216
> This would be mainly useful together with IMPALA-572 that would allow writing profiles to  files as printing the binary format to stdout is not too helpful. E.g.
> impala-shell --profile_format=thrift --profile_output=/tmp/impala_profile_log
> A reason to do this is to get all counters if aggregated profiles are used, as the default text format is "lossy" in this case.
> Using the same format as Impala's profile log would allow processing these files with impala-profile-tool.
> A few more ideas that could improve this:
> - supporting json format
> - allowing to set this option runtime (set profile_output=/tmp/impala_profile_log)
> - allow place holders in the file name to create a new file for each query (e.g. date or queryid)
