[jira] [Commented] (ACCUMULO-1412) Allow shell password to come from a variety of sources

["Mike Drob (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-1412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13660984#comment-13660984 ] 

Mike Drob commented on ACCUMULO-1412:
-------------------------------------

I started working on this using JCommander (and got a functioning prototype) before realizing that the shell still uses Apache CLI. Is it worth refactoring to take advantage of some of the niceness of JCommander, considering that a bunch of the other utility classes already have made the switch in ACCUMULO-745

> OpenSSL allows the user to read the password from a number of places, including a file, environment variable, file descriptor, command line argument, or standard in. It would be nice for accumulo to do the same, to ease scripting while still not revealing password through {{ps}} or it's brethren.
> A logical way to implement this might be using a [JCommander Custom Type|http://jcommander.org/#Custom_types] for the password field.
