             Summary: Create HiveConf per application instead of per query in HiveQl.scala
                 Key: SPARK-7331
                 URL: https://issues.apache.org/jira/browse/SPARK-7331
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 1.3.0, 1.2.0
            Reporter: Nitin Goyal
            Priority: Minor


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.
