> 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).
