      Description

      For users, if they want the table schema for what they are reading they need to do the following:
      this.schema = HCatInputFormat.getTableSchema(context);

      For their output they do the same but for HCatOutputFormat:
      this.schema = HCatOutputFormat.getTableSchema(context);

      The HCatOutputFormat.getTableSchema throws an IOException and the HCatInputFormat.getTableSchema throws just Exception. This is caused by
      "private static InputJobInfo getJobInfo(JobContext jobContext) throws Exception" in HCatBaseInputformat

      This method should match the HCatBaseOutputFormat's version which throws the following
      throw new HCatException(ErrorType.ERROR_NOT_INITIALIZED);
