While we want to be fault tolerant, there's a point where we want to eventually fail. I know we have a couple never ending retry loops that need to be addressed (https://issues.apache.org/jira/browse/ACCUMULO-1268), but I'm unsure if queries suffer from this problem.
Unfortunately, fault tolerance is a bit at odds with instant notification of system issues, since some of the fault tolerance is temporally oriented. And that ticket lacks context of it never failing out vs. failing out eventually (but too long for the user) On Sun, Jan 24, 2016 at 7:46 PM Christopher <[email protected]> wrote: > I saw this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1300987 > > As far as I can tell, they are reporting normal, expected, and desired > behavior of Accumulo as a bug.
