The commit is not actually written to the log. The log is updated before a
server ACKs a proposal - and what's in the log is what matters for
recovery.
In your example, server1 sent a commit for p2, so it got at least one ACK
from server2 or server3. Since in your example server2 has been elected,
Hi,
I tried to migrate a lab environment from Zookeepr 3.4.14 (used for Solr)
to 3.5.5 and encountered an issue. It is ZooKeeper in standalone mode
(other environments have a proper ensemble). I increased jute.maxbuffer
beyond the default (but not excessively) - this was working perfectly fine

thank you for the quick reply. They read from the same disk paths and have
the same access rights (in fact the RHEL service executes them as the same
specific user).

It also seems that 3.5.5 does not attempt to read all of the logfiles (I
have to still confirm), but the two it reads exist, it has access and they
are much more than 0 byte

We should have the stackstace of the EOFException.

Something is broken!
This is expected behavior introduced in ZOOKEEPER-2325. We don't want to
end up with potential inconsistent state across the ensemble when
recovering from empty snapshot.
To continue upgrade, just delete al

If there are local snapshot files and the files are valid, then it's a bug
that server fails to load them.

Not I am aware of. There are some format changes (added compression
ok, then let me verify tomorrow if a snapshot file is indeed there. If it
is missing then I wonder why it was missing. There was no crash or whatever
and 3.4.14 works without issue, but of course it could have loaded them
from the log files. However, then I wonder why it does not create one.

Hi,
I am using the new Solr 8.2.0 with SolrCloud and external ZooKeeper 3.5.5.
However, after adding in the line under zoo.cfg
*4lw.commands.whitelist=**
I get the error under Cloud -> ZK Status in Solr
*"Errors: - membership: Check 4lq.commands.whitelist setting in zookeeper
configuration file.
Maybe the Solr mailing list should address this.

Thanks. It is possible to force Zookeeper to create a snapshot? I will check I
