------------------------------------
I also encountered the same problem with hive UDAF queries such as PERCENTILE
and ASSERT_TRUE. I have applied given patch and run these 2 queries. This patch
fails throwing following excetiption.

Correct me if I am wrong ,
With my understanding problem is adding URI's into 'taskLogUrls', I feel we
need null check while adding URI into 'taskLogUrls' because hadoop23shims
returns null if the cluster is MR2. This URI construction fails since null is
passed as argument when TaskLogProcessor.getErrors() or
TaskLogProcessor.getStackTraces() is called and throws MalformedURLException.
