Description

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).
