Hi
I am running Hadoop 2.4.1 with YARN HA enabled (two name nodes, NM1 and NM2).
When verifying ResourceManager failover, I use “kill -9” to terminate the
ResourceManager in name node 1 (NM1), if I run the the test job, it seems that
the failover of ResourceManager keeps trying NM1 and NM2
Hi,
If I have TWO nodes for ResourceManager HA, what should be the correct steps
and commands to start and stop ResourceManager in a ResourceManager HA cluster ?
Unlike ./sbin/start-dfs.sh (which can start all NNs from a NN), it seems that
./sbin/start-yarn.sh can only start YARN in a node at
Hey, Arthur:
Did you use single node cluster or multiple nodes cluster? Could you
share your configuration file (yarn-site.xml) ? This looks like a
configuration issue.
Thanks

it is a multiple-node cluster, two master nodes (rm1 and rm2), below is my

Q1) I need start yarn in EACH master separately, is this normal? Is there
a way that I just run ./sbin/start-yarn.sh in rm1 and get the
STANDBY ResourceManager in rm2 started as well?
No, need to start multiple RMs separately.
Q2) How to get alerts (e.g. by email) if the ACTIVE

Thank y very much!
At the moment if I run ./sbin/start-yarn.sh in rm1, the standby STANDBY

Hi
I have set up the Hadoop 2.4.1 with HDFS High Availability using the Quorum
Journal Manager.
I am verifying Automatic Failover: I manually used “kill -9” command to disable
all running Hadoop services in active node (NN-1), I can find that the Standby
node (NN-2) now becomes ACTIVE now
You need additional settings to make ResourceManager auto-failover.
http://hadoop.apache.org/docs/r2.4.1/hadoop-yarn/hadoop-yarn-site/ResourceManagerHA.html
JobHistoryServer does not have automatic failover feature.
