      Description

      I am getting zero exit code when there is a real exception when
      running Sqoop Import. The correct exit code (whether it is error or
      not) is important for our scheduling system to notify us of any
      errors. Should I file a jira issue for this bug?
      Here is what I get:

      For a regular sqoop command:

      [cloudera@localhost workhive]$ sqoop
      Warning: /usr/lib/hbase does not exist! HBase imports will fail.
      Please set $HBASE_HOME to the root of your HBase installation.
      Try 'sqoop help' for usage.
      [cloudera@localhost workhive]$ echo $?
      1
      

      So, the error code is correct here

      But for the import:

      [cloudera@localhost workhive]$ sqoop import --username
      username--password password--hive-import --table ExternalPublisher
      --connect jdbc:sqlserver://url:port;databaseName=DBName;
      Warning: /usr/lib/hbase does not exist! HBase imports will fail.
      Please set $HBASE_HOME to the root of your HBase installation.

      [cloudera@localhost workhive]$ echo $?
      0
      

      The error code shows success here, which is undesirable. And I am not
      interested in why I get FileAlreadyExistsException, I know how to
      handle it. The correct error code is more important for maintenance.
