Carl Steinbach commented on HIVE-2090:
--------------------------------------
bq. [exec] .../metastore/if/hive_metastore.thrift:212] optional keyword is
ignored in argument lists.
Looks like this was added here:

Modify Thrift parser to disallow optional/required keywords in argument lists
Reviewed By: dreiss
Test Plan: Toss an optional/required in an arg list,
check that it's ignored and compiler spits a warning
git-svn-id: https://svn.apache.org/repos/asf/incubator/thrift/trunk@665255
13f79535-47bb-0310-9956-ffa450edef68
{code}
The comments seem to indicate that Thrift does not actually support optional
parameters or default parameter values for optional parameters, which implies
that we're depending on undocumented and unintended behavior that can change at
any time. Can you please ask Mark or David about this checkin and see what they
say?
Thanks!
