     private def executeHQL(realCode: String, driver: HiveDriverProxy): ExecuteResponse = {
       var needRetry: Boolean = true
       var tryCount: Int = 0
       var hasResult: Boolean = false
       var rows: Int = 0
       var columnCount: Int = 0
       while (needRetry) {
         needRetry = false
         driver.setTryCount(tryCount + 1)
         val startTime = System.currentTimeMillis()
         try {
           Utils.tryCatch {
             val queryPlan = driver.getPlan
    ...
   ```
   The above code is in branch : dev-1.3.2 ,because we skip driver.compile() step , driver.getPlan method will throw NPE , any suggest in fixing NPE ?
