-- --schema doesn't work with Sqoop create-hive-table

HDP-2.5.0.0 using Ambari 2.4.0.1

I'm able to create a table in HCatalog from a SQL Server source db, for example :

sqoop import --null-string '\\N' --null-non-string '\\N' --hive-delims-replacement '\0D' --hcatalog-home /usr/hdp/current/hive-webhcat --hcatalog-database MS_Management_Coaching --hcatalog-table TripAggregate --create-hcatalog-table --hcatalog-storage-stanza 'stored as orc tblproperties ("orc.compress"="ZLIB")' --validate --connect 'jdbc:sqlserver://<DB server>;database=Management' --username uname--password pwd--table TripAggregate -- --schema Coaching

but when I try to use a the --create-hive-table, the -- --schema option doesn't work, no matter where I position it :

-bash-4.2$ sqoop create-hive-table --hive-database test --connect 'jdbc:sqlserver://<DB Server>;database=Management' --username uname--password pwd--table TripAggregate -- --schema Coaching

If the argument -- is given on the command-line, then subsequent arguments are sent directly to the underlying tool.

After looking into sqoop code, I found that in --create-hive-table flow does not go to the underlying tool. That's why you are not able to use -- --schema in your command.

Useful part of source code for ImportTool :

 public void validateOptions(SqoopOptions options)
      throws InvalidOptionsException {

    // If extraArguments is full, check for '--' followed by args for
    // mysqldump or other commands we rely on.
    options.setExtraArgs(getSubcommandArgs(extraArguments));
    int dashPos = getDashPosition(extraArguments);

    if (hasUnrecognizedArgs(extraArguments, 0, dashPos)) {
      throw new InvalidOptionsException(HELP_STR);
    }

    validateImportOptions(options);
    validateIncrementalOptions(options);
    validateCommonOptions(options);
    validateCodeGenOptions(options);
    validateOutputFormatOptions(options);
    validateHBaseOptions(options);
    validateHiveOptions(options);
    validateHCatalogOptions(options);
    validateAccumuloOptions(options);
  }

Useful part of source code for CreateHiveTable :

 public void validateOptions(SqoopOptions options)
      throws InvalidOptionsException {

    if (hasUnrecognizedArgs(extraArguments)) {
      throw new InvalidOptionsException(HELP_STR);
    }

    validateCommonOptions(options);
    validateOutputFormatOptions(options);
    validateHiveOptions(options);

    if (options.getTableName() == null) {
      throw new InvalidOptionsException(
          "--table is required for table definition importing." + HELP_STR);
    }
  }

you see no checking for -- args is done in the later.


Edit:

--hive-import by default creates hive table and you can use -- --schema with import command. If you want sqoop to create hive table for you and import data in that table. It should work for you.
