Hi Shawn, That is not possible at this time.
Will it be ok, if remote the zookeeper dependencies (jars) from solr and replace it with 3.5.5 jars? Thanks in advance. ________________________________ From: Shawn Heisey <apa...@elyograg.org> Sent: Monday, March 1, 2021 11:17:24 PM To: solr-user@lucene.apache.org <solr-user@lucene.apache.org>; u...@zookeeper.apache.org <u...@zookeeper.apache.org> Subject: Re: Zookeeper 3.4.5 with Solr 8.8.0 On 3/1/2021 6:51 AM, Subhajit Das wrote: > I noticed, that Solr 8.8.0 uses Zookeeper 3.6.2 client, while Solr 6.3.0 uses > Zookeeper 3.4.6 client.

The ZK project guarantees that each minor version (X.Y.Z, where Y is the same) will work with the previous minor version or the next minor version. 3.4 and 3.6 are two minor versions apart, and thus compatibility cannot be guaranteed. See the "backward compatibility" matrix here: https://cwiki.apache.org/confluence/display/ZOOKEEPER/ReleaseManagement I think you'll need to upgrade your ZK server ensemble to fix it. Thanks, Shawn
