Hi All,

I have 4 node server environment, 3 Data node and 1 Non data node.

I am indexing a file with the following settings

shard = 6  
replica=1

After complete indexing operation, the file size in each node is not  
equally shard.

Total index size=50

First node size - 28gb  
Second node size - 14gb  
Third node size- 8gb

Questions:

1. Is there any ratio where the index file is shared between the  
nodes...?
2. What we need to do to share the Index content equal to all  
available nodes ?

I have 20gb of ram settings in each node while working on that index  
it exceeds the allocated memory.....

Questions:

1. Why does it exceeds the allocated memeory...?
2. How to calculate RAM size....? Is it based on the index  
size........?

thanks...
