Hi,
Thanks for the response, sorry i put this email in the dev space.
My data replication is 2. and yes the region and master server connectivity
is good
Initially i started with 4 data nodes and 1 master, i faced the same
problem. So i reduced the data nodes to 1 and wanted to test it. I see the
same issue. I haven't tested the pseudo distribution mode, i can test that.
But my objective is to test the full distributed mode and do some testing.
I can send my configuration for review. Please let me know if i am missing
any basic setup configuration.
