Multiple master problem in elasticsearch 0.90.10


(Ankit Mittal) #1

Hi All,

I am using 2 master node in my elasticsearch cluster and 2 data node. I ma
using 2 RHEL server ( 1 master + 1 data node on each )

When i setup the above it is working fine for some time around 15 - 20
hours. but after then my cluster health is yellow.
and the no available shards are reduce to half. when i check the
elasticsearch data and master node , all 4 are running fine.

Please help me in resolving the above issue.
The requirement was to implement elasticsearch cluster on two server, for
high availability ( 2 master on different server and 2 node on different
server ).

Please let me know if someone implemented high availability different from
the above

Thanks
Ankit Mittla

There should be no need to run a master and a data node on each machine.
Only two masters is not enough to reliably form a consensus and you are
only taking away processing power from the data node.
