Nitin Goyal updated SPARK-7331:
-------------------------------
Description:
A new HiveConf is created per query in getAst method in HiveQl.scala
def getAst(sql: String): ASTNode = {
/*
* Context has to be passed in hive0.13.1.
* Otherwise, there will be Null pointer exception,
* when retrieving properties form HiveConf.
*/
val hContext = new Context(new HiveConf())
val node = ParseUtils.findRootNonNullToken((new ParseDriver).parse(sql,
hContext))
hContext.clear()
node
}
Creating hiveConf adds a minimum of 90ms delay per query. So moving its
creation in Object such that it gets initialised once.
