@srowen I find error message in test bulid log, a OutOfMemoryError
exception has happened. The code in 71 line of the file AsyncRDDActions.scala
is "val results = new ArrayBuffer[T](num) ", because num(2147483638) is too
large, JVM can't allocate enough memory space. I think I should modify unit
test to smaller num in 2079 line of SQLQuerySuite.scala.
error message:
[info] Exception encountered when attempting to run a suite with class
name: org.apache.spark.sql.SQLQuerySuite *** ABORTED *** (31 seconds, 447
milliseconds)
