Thejas M Nair commented on HIVE-5133:
-------------------------------------
Thanks for the feedback, I will create a new patch addressing these comments. I
also need to add e2e tests.
Note about the patch - With this change for submitting pig or MR jobs you need
to specify usehcatalog=true as a POST param. (in curl command " -d
usehcatalog=true" ). In case of pig this argument is option, it is sufficient
that you have a arg='-useHCatalog' POST param.
> webhcat jobs that need to access metastore fails in secure mode

>
> Webhcat job submission requests result in the pig/hive/mr job being run from
> a map task that it launches. In secure mode, for the pig/hive/mr job that is
> run to be authorized to perform actions on metastore, it has to have the
> delegation tokens from the hive metastore.
> In case of pig/MR job this is needed if hcatalog is being used in the
> script/job.
