Subject new "nodetool ring" output and unbalanced ring?
Date Thu, 06 Sep 2012 17:54:20 GMT

I recently upgraded from 0.8.x to 1.1.x (through 1.0 briefly) and nodetool
-ring seems to have changed from "owns" to "effectively owns".
 "Effectively owns" seems to account for replication factor (RF).  I'm ok
with all of this, yet I still can't figure out what's up with my cluster.
 I have a NetworkTopologyStrategy with two data centers (DCs) with
RF/number nodes in DC combinations of:
DC Name, RF, # in DC
analytics, 1, 2
us-east, 3, 4
So I'd expect 50% on each analytics node, and 75% for each us-east node.
 Instead, I have two nodes in us-east with 50/100??? (the other two are
75/75 as expected).

Here is the output of nodetool (all nodes report the same thing):
Address         DC          Rack        Status State   Load
 Effective-Ownership Token

x.x.x.x   us-east     1c          Up     Normal  94.57 GB        75.00%
x.x.x.x   analytics   1c          Up     Normal  60.64 GB        50.00%
x.x.x.x   us-east     1c          Up     Normal  131.76 GB       75.00%
x.x.x.x    us-east     1c          Up     Normal  43.45 GB        50.00%
x.x.x.x    analytics   1d          Up     Normal  60.88 GB        50.00%
x.x.x.x   us-east     1d          Up     Normal  98.56 GB        100.00%

If I use cassandra-cli to do "show keyspaces;" I get (and again, all nodes
report the same thing):
Keyspace: civicscience:
  Replication Strategy: org.apache.cassandra.locator.NetworkTopologyStrategy
  Durable Writes: true
    Options: [analytics:1, us-east:3]
I removed the output about all of my column families (CFs), hopefully that
doesn't matter.

Did I compute the tokens wrong?  Is there a combination of nodetool
commands I can run to migrate the data around to rebalance to 75/75/75/75?
 I routinely run repair already.  And as the release notes required, I ran
upgradesstables during the upgrade process.

Before the upgrade, I was getting analytics = 0%, and us-east = 25% on each
node, which I expected for "owns".
