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?
> Thrift gateway should propagate text from exception causes.

> 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.
