> ----------------------------------------------

> Key: SPARK-14538
> URL: https://issues.apache.org/jira/browse/SPARK-14538
> Project: Spark
> Issue Type: Bug
> Reporter: Davies Liu

> The default stack size of 64-bit JVM is 1M, the new SQL parser may fail as StackOverflow if the SQL query is very long. Also the anaylizer/optimizer very deep stacks, it may also fail on complicated query.
> We should increase the default stack size for Spark (at least for driver) to 2M or 4M.
> The down side of this is that we will increase the memory usage for each thread. Right now, a fresh new spark-shell (with HiveContext) take 814M on my mac, it increased to 886M if it change the stack size to 4M (about 20+ threads).
