The documentation is not clear. All blog post examples about Hive LLAP (Long Live and Process) uses the Tez execution engine, but can Spark/MR hive engines also use LLAP?

Hive2 has deprecated MR execution, but all are still possible

Tez is the first class execution engine because Hive on Spark is still under active development

  • Haven't tried it. You tell me. The property still exists. https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution Note: Tez requires less resources than Spark and when benchmarked running queries on ORC+ZLIB format vs SparkSQL on Parquet+Snappy, Tez is faster – OneCricketeer Mar 11 '18 at 15:26
