[jira] [Commented] (ACCUMULO-3094) Pass back stack traces when server side exception occurs

["Christopher Tubbs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-3094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14119182#comment-14119182 ] 

Christopher Tubbs commented on ACCUMULO-3094:
---------------------------------------------

Yeah, I like the idea of a development mode, like is common for web servers / frameworks, as [~elserj] points out, but the default should be off, like [~kturner] said. This should be a server-side configuration (general.server.stacktrace.verbosity=(none, partial, full)?). Clients shouldn't be able to choose how much detail is returned. It should be a mode that an admin chooses, either with a restart, or (maybe) a live configuration change.

> Was discussing ACCUMULO-3092 w/ [~dlmarion] and the issue of why more info about server side exceptions was not transmitted back to client came up.  This was a concious design decision made in Accumulo to avoid unintentionally leaking information to the client.   The main concern is the exception message on the server side, that message could have been constructed w/ data from Accumulo.
> We discussed the possibility of dropping the exception message[s] and sending the stack trace[s] back to the client side.
