Hi,
We have a production solr cluster setup with 4 shards and 4 replicas on a
legacy stack.
Same machines have been used to host 5 Zookeeper nodes ensemble.
Solr version : 1.1.0.41
ZK version : 3.4.6
I saw in a later message that the Solr version is actually 4.8.1.
Solr 4.8.1 was announced on May 20, 2014. Precisely ten years ago
today. You're definitely going to need to update that. Solr 4.x has
been end of life for quite a while.
The error message you later included looks like it is probably
incomplete. It is probably MANY lines longer, and we need all of them
to have any idea why Solr failed to properly start up. It is better to
get those error messages from the Solr log file, but as we did not have
any kind of startup script in those days, I have no way of knowing
whether a logfile has even been created or where it might live.
Note that when you DO upgrade Solr, you're not going to be able to use
your existing index in 6.x and later. It will need to be built again
from scratch.
Thanks,
Shawn
