Yeah, our memory usage is drastically different since the upgrade. We are seeing spikes in heap utilization on tablet servers that weren't happening before the upgrade despite our ingest load being roughly the same. This increase in heap utilization seems to be causing long GC times. Those GC times are long enough that the tablet servers lose their locks and then die.
Looking into the JVM options, we don't see anything obvious that changed around the garbage collector, and looking at the Accumulo release notes didn't leave us any indication that something like this should have changed, but nevertheless we are seeing crashes of tservers. I'm mostly trying to identify whether or not rollback is even an option. - Logan On Fri, Nov 4, 2022 at 3:49 PM Dave Marion <dmario...@gmail.com> wrote: > Are you running into an error or some other issue that is making you > think that you have to rollback?
