Change subject: IMPALA-4899: Fix parquet table writer dictionary leak
......................................................................


Patch Set 4:

> is there a way to ascertain the leak-free behavior in a test?

I don't see a difference in the runtime profile with this patch vs without. The 
way I have been testing is by hand. I do a clustered insert into a partitioned 
table and look at the memory usage in top. It is a very clear difference, but 
I'm not sure how to write a test around it. I tried setting a mem_limit and 
testing without my patch, but the mem_limit is not enforced.
