Hi,
We have a Solr Cloud cluster running 8.11.2 on 16 servers that have just
been upgraded to Ubuntu 20.04 (from 18.04).
It looks like we are getting shards down/recovering more often than
previously, so I'm wondering what version of Java and which garbage
collector is recommended on Ubuntu 20
Can you say something about the root cause for solr processes to crash? Are
they killed by Linux?
Which version of Java did you run on 18.04? Other changes done at the same
time, such as OS-level settings for ulimits, vm.max_map_count, swappiness etc.
If you have not fine-tuned your JVM settings

They are usually not crashing, I "just" see shards go into down/recovery
state.
Some of the time they recover without intervention, some of the time a
shard or two stays down, and on

Hello - I want to know how it is possible to create indexes for a certain
attribute (and its different values) of a document, using Java.
Thanks.

This is a pretty vague question. We need details of exactly what you're
trying to do and what the environment look

Ok, good.

Sounds like we're on the right track version-wise then.

In, java i want to create index of a collection named person and say an
"Age" attribute for the values between 20 and 35. so that when i query Solr
on those values it retrieves them quickly how to do that ?
