Subject [jira] [Commented] (HDFS-13577) RBF: Failed mount point operations, returns wrong exit code.
Date Tue, 16 Jul 2019 14:25:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16886154#comment-16886154
] 

Ayush Saxena commented on HDFS-13577:
-------------------------------------

This seems fixed ::


{code:java}
      if (!added) {
        System.err.println("Cannot add mount point " + mount);
      }
      return added;
{code}

The said message shall be printed when added is false, and same false is returned.

Then ::


{code:java}
 if (addMount(argv, i)) {
          System.out.println("Successfully added mount point " + argv[i]);
        } else {
          exitCode = -1;
        }
{code}

Here addMount(argv,i) receives response as False, Moves to else, sets exit code to -1.

Verified, Seems not an issue now. Can resolve this now!!!
