---------------------------------
Summary: Add config property to disable incremental collection
used in Thrift server
Key: SPARK-2591
URL: https://issues.apache.org/jira/browse/SPARK-2591
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Cheng Lian
Priority: Minor
{{SparkSQLOperationManager}} uses {{RDD.toLocalIterator}} to collect the result
set one partition at a time. This is useful to avoid OOM when the result is
large, but introduces extra job scheduling costs as each partition is collected
with a separate job. Users may want to disable this when the result set is
expected to be small.
