[jira] [Updated] (NUTCH-1914) Improve error messages of segment dumper tool

["Tyler Palsulich (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/NUTCH-1914?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tyler Palsulich updated NUTCH-1914:
-----------------------------------
    Attachment: NUTCH-1914.palsulich.1-12-15.diff

Patch with two small fixes:
* If there is an error parsing the command line, the exception message is printed to standard error.
* Remove the unnecessary {{@SuppressWarnings("static-access")}} annotations.

With this patch, if you enter an invalid command:
{code}
➜  ./nutch dump -invalid
Unrecognized option: -invalid
{code}

> The segment dumper from NUTCH-1526 is useful. But, if you enter an invalid option (e.g. {{./nutch dump -invalid}}), nothing is printed.
