Dear all,
We've tried to use sparkSql to do some insert from A table to B table
action where using the exact same SQL script,
hive is able to finish it but Spark 1.3.1 would always end with OOM issue;
we tried several configuration including:
--executor-cores 2
--num-executors 300
--executor-memory 7g
sconf.set("spark.storage.memoryFraction", "0")
but none of them can change the result of error:
java.lang.OutOfMemoryError: GC overhead limit exceeded
is there any other configuration we can make? Thanks!
