Subject [jira] [Commented] (HBASE-13419) Thrift gateway should propagate text from exception causes.
Date Thu, 09 Apr 2015 20:20:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14488193#comment-14488193
] 

Michael Muller commented on HBASE-13419:
----------------------------------------

I can see a case for it and against it. I think it depends a lot on how users will generally
display their exception text.  If it's printed to the console, it's probably better to use
newlines.  If it's written to a log-file, maybe not.

Would you prefer that I switched it to newlines?

> Exceptions passed back from the thrift gateway only include the message text of the toplevel
exception.  Information from the cause chain is lost.
> In some cases, the top-level exception text is useless but there is some very specific
and useful information provided in some of the cause exceptions, so it would be very helpful
to flatten all of the messages into the exception text returned to the user.
