 If the mapjoin.mapreduce optimization kicks in on a query of this form:
 {noformat}
 select count(distinct a.v) 
 from a join b on (a.k = b.k)
 group by a.g
 {noformat}
 The planer will NPE in the metadataonly optimizer.

Problem is that mapjoin.mapreduce optimization leaves un-configured tablescan 
in the plan. The metadata only optimization will choke on that. Patch .1 strips 
the TS operator out of the plan after merging the child map task into the 
current task.
