Balazs Hevele reassigned IMPALA-14673:
--------------------------------------
Assignee: Balazs Hevele
> Allow downloading Thrift profiles in impala-shell
> -------------------------------------------------
>
> Key: IMPALA-14673
> URL: https://issues.apache.org/jira/browse/IMPALA-14673
> Project: IMPALA
> Issue Type: New Feature
> Components: Clients
> Reporter: Csaba Ringhofer
> Assignee: Balazs Hevele
> Priority: Major
> Labels: ramp-up
>
> 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)
