Re: How to balance this cluster out ?

2014-05-15 Thread Aaron Morton
This is not a problem with the token assignments. Here is the ideal assignments 
from the tools/bin/token-generator script 

DC #1:
  Node #1:0
  Node #2:   56713727820156410577229101238628035242
  Node #3:  113427455640312821154458202477256070484

You are pretty close, but the order of the nodes in the output is a little odd, 
would normally expect node 2 to be first.

First step would be to check the logs on 1 to see if it’s failing at 
compaction, and to check if it’s holding a lot of hints. Then make sure repair 
is running so the data is distributed. 

Hope that helps.

 Obviously, the first node in 1b has 40% more data than the others. If I

 the tokens accomplish what I need and which tokens ?

How to balance this cluster out ?
