Hi Adam,
We run Hbase 2.5.12 with Java17. We use a rather small heap size, because
we rely on off heap read(bucket cache) and off heap write paths.
Apart from the defaults our hbase-env.sh contains just the very basics for
G1GC
export HBASE_REGIONSERVER_OPTS="-XX:+UseG1GC -XX:MaxGCPauseMillis=50 \
-Xms4G -Xmx4G \
$HBASE_REGIONSERVER_OPTS"
and also "export HBASE_OFFHEAPSIZE" in our case.
Best,
