I don't know what could go wrong, so it's hard to say that it would be
obvious.
For what it's worth, if we can identify a performance bug, we can release a
fix in a 1.10.3, so you can upgrade instead of downgrade.

Thanks all,
We have a test system that we could try rolling back. If something does
break, will it be obvious?
Dave, the ingest rates are slightly more spikey, but I think it's mostly
because tservers are bouncing and the cluster is working to catch up.
Nothing major jumps out as an increase in
I don't think it has any changes that would prevent rollback, but it's not
a scenario that has been tested to my knowledge.

It's going to take some time to review the changes[1], but I don't see
changes in the default JVM sizes. I was wondering if maybe the issue is
that it's running faster. You are loading the same amount of data, but is
it going faster by chance? If so, you could be creating more garbage per
unit
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
Are you running into an error or some other issue that is making you
think that you have to rollback? I don't know that rolling back has been
tested.

Hello:
We recently upgraded from Accumulo 1.9.3 to 1.10.2. Is it safe to roll back
to Accumulo 1.9.3?
Thanks in advance,
