Subject Re: Hadoop 2.4.1 Verifying Automatic Failover Failed: ResourceManager
Date Mon, 11 Aug 2014 16:45:13 GMT
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 a time.

Regards
Arthur

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 non-stop.
