Subject [jira] [Reopened] (ACCUMULO-670) BatchWriters do not track Throwables beyond Constraint Violations
Date Tue, 19 Feb 2013 21:57:12 GMT


Keith Turner reopened ACCUMULO-670:

It seems like this change breaks the public API.  Changing the return of an existing method
will break code that worked against 1.5.

> Working on ACCUMULO-259 and adapting the Security Random Walk test to account for cached
credentials, to prevent it from crapping out on ambiguous credentials (credentials which are
currently propagating). And I noticed that our client side Writers provide no means of feedback
to the client if there is a non-ConstraintViolationException.
> That is, looking at the TabletServerBatchWriter specifically, we keep track of which
servers had errors, which key extents had errors, and what ConstrainViolations we saw, but
we don't actually track the actual Throwables we get, aside from ConstraintViolation. We should
keep a Collection or Set of the Throwables we see so client code can do proper case checking
as well.
