Hi Serega,
Do you have enough resources allocated for each VM? Just some swapping on
the VMs or the host can make things unstable. Also from the number of
services on each VM sounds like your host should have at least 12GB of free
RAM just for running things smoothly otherwise you might want to
Ok, thanks, we'll check it.

Hi, I have PoC HBase cluster running on 3 VM

HDFS was working, no alerts were there
ZK server was

heavy load - considering the number of daemons running on that node.
Please check GC log.
Cheers

Hi, HBase was down during 08:25 to 09:15
I was looking into logs, and thinking. I've tried to find something more
clever. than dummy restart.
We are using Cloudera distro, each of daemons run in it's own JVM.
I'll try to find CPU load logs.
There is really low load,
