---------------------------------
Summary: Spark's HiveThriftServer should be able to use multiple
sqlContexts
Key: SPARK-16795
URL: https://issues.apache.org/jira/browse/SPARK-16795
Project: Spark
Issue Type: Wish
Affects Versions: 2.0.0
Reporter: Furcy Pin
It seems that when sending multiple Hive queries to the thrift server, the
server cannot parallelize the query plannings, because
it uses only one global sqlContext.
This make the server very inefficient at handling many small concurrent queries.
It would be nice to have it use a pool of sqlContexts instead, with a
configurable maximum number of contexts.
