   1. Open /opt/omni-operator/hive/conf/omni.conf.

      vi /opt/omni-operator/hive/conf/omni.conf

   2. Press I to enter the insert mode and add the following Hive configurations (recommended).

      # <----Other properties---->
      enableBatchExprEvaluate=false
      # <----Hive properties---->
      EmptySearchStrReplaceRule=REPLACE
      CastDecimalToDoubleRule=CONVERT_WITH_STRING
      ZeroStartIndexSupportRule=IS_SUPPORT
      SupportContainerVecRule=SUPPORT
      StringToDateFormatRule=NOT_ALLOW_REDUCED_PRECISION
      NegativeStartIndexOutOfBoundsRule=EMPTY_STRING
