Migrating from Hive on MR to Hive on Spark
I'm wonder how hive + oozie action[oozie:hive2-action:0.1] on Spark[set hive.execution.engine=spark] based ran is much slower than Hive on MapReduce.
Note: I included set hive.execution.engine=spark; in my queries and in oozie included hive2-action:0.1 in [xmlns] + provided jdbc[url]. The code is running successfully, i saw logs but it takes much clock time than usual MR.
