Subject:Re: HBASE -- RS expire?
Is your ZK managed by HBase or are you managing it yourself?
BTW - All ZK nodes should be reachable by all nodes in the cluster.
The YouAreDeadException would be in RS logs if at all.

Is it a good or bad option?
What are the pros and cons about each one.

Finally my HMaster has stabilized and been running for 7 hours. I
believe my networking issues are behind me now. Thank you everyone for
the help.
New issue is my RSes continue to die after about 20 minutes. Again the
cluster is idle. No jobs are running and I get this on all of my RSes

Awesome.
Looks like the same issue is biting you with the RS too. The RS isn't
I don't see that in the RS logs. Would I see that in the ZK logs?
At this point there is no network. Just a switch. I reduced the number
of nodes to 40 and had all of them placed on the same switch with a
single vlan. I even had the network techs use a completely different
switch just to be
The timeout can be configured using the session timeout configuration. The
default for that is 180s, but that means that if the RS doesn't heartbeat to ZK
for 180s, it's considered dead. Unless the machines are really loaded or GCs
are pausing the RS processes, I don't see any other reason
Funny you mention that. I asked the techs to set it up that why.
I went to pull my ZK logs and found that 1 RS is still running. What is
interesting is that RS is connected to ZK on devrackA-05. The 2 RSes
that died where connected to ZK on devrackA-03. devrackA-03 has ZK and
HMaster on it.
