-------------------------------------
Attached escape2.q.out because the diff for some reason thought it was a binary
file.
> Stop testing concat of partitions containing control characters.

> We have been, for a short while, testing to make sure that concatenation
> commands work with partitions that contain ASCII control characters. This
> happened to work up until recently due to a happy coincidence in the way the
> Hive object's HiveConf was updated. Namely, it was updated often enough that
> it got configs set by the user, but not so often that it got the value for
> hive.query.string. With some recent changes, it now needs to be updated more
> often, see https://issues.apache.org/jira/browse/HIVE-2918
> This breaks the process of launching a job to merge partitions that contain
> ASCII control characters. The job conf is constructed using the updated Hive
> conf containing the value of hive.query.string which contains ASCII control
> characters. When the job conf is converted to XML it fails because these
> characters are illegal. Given that any query has, even prior to this change,
> failed when that query contained ASCII control characters, and hence these
> partitions cannot be queried directly, it seems reasonable to no longer
> support concatenating them either (which this change will allow for).
