I'm getting the following error using the HDP sandbox version 2.5

python --version
Python 2.7.5
hive --version
Hive 1.2.1000.2.5.0.0-1245
hadoop version
Hadoop 2.7.3.2.5.0.0-1245

@karlarao I came across this same issue, but it looks like it was because I'm using MR and not Tez.

Any plans to have this updated for Tez?
