Hive on spark doesn't work in hue - hive

Question

I am trying to trigger hive on spark using hue interface . The job works perfectly when run from commandline but when i try to run from hue it throws exceptions. In hue, I tried mainly two things:
1) when I give all the properties in .hql file using set commands
set spark.home=/usr/lib/spark;
set hive.execution.engine=spark;
set spark.eventLog.enabled=true;
add jar /usr/lib/spark/assembly/lib/spark-assembly-1.5.0-cdh5.5.1-hadoop2.6.0-cdh5.5.1.jar;
set spark.eventLog.dir=hdfs://10.11.50.81:8020/tmp/;
set spark.executor.memory=2899102923;
I get an error
ERROR : Failed to execute spark task, with exception 'org.apache.hadoop.hive.ql.metadata.HiveException(Unsupported execution engine: Spark. Please set hive.execution.engine=mr)'
org.apache.hadoop.hive.ql.metadata.HiveException: Unsupported execution engine: Spark. Please set hive.execution.engine=mr
2) when I give properties in hue properties, it just works with mr engine but not spark execution engine.
Any help would be appreciated

I have solved this issue by using a shell action in oozie.
This shell action invokes a pyspark action bearing my sql file.
Even though the job shows as MR in jobtracker, spark history server recognizes as a spark action and the output is achieved.
shell file:
#!/bin/bash
export PYTHONPATH=`pwd`
spark-submit --master local testabc.py
python file:
from pyspark.sql import HiveContext
from pyspark import SparkContext
sc = SparkContext();
sqlContext = HiveContext(sc)
result = sqlContext.sql("insert into table testing_oozie.table2 select * from testing_oozie.table1 ");
result.show()
