Hi  
I am trying to get around the issue of failover by running multiple  
instances over same data , by running two elasticsearch instances on a  
machine , both having the same data directory , with both nodes being  
masters , and 2nd node , not handling the data (node.data=false).

Even if one of the nodes is not a data node, elasticsearch still creates  
its directory ([0] , [1]) etc , in the common data directory , (what i  
expected was only one sub directory ([0] (only for the data node) ) in the  
common directory , with both the nodes being able to search the common  
source.

in current case , when both instances are running , the search is fine ,  
but when the data node fails , the search returns shards failure exception  
, as non-data node searches in it's sub directory([1]) , (which does not  
contains the data).

Could somebody please help me resolve the issue ?

Thanks  
Tarang Dawer

Use two data nodes, and to ensure replication, on two machines.

You can not search or index data on a non-data node. A non-data node  
just forwards the request to a data node.

Can you explain why you use two nodes on a single machine? This makes  
not much sense.
