Subject Re: Multiple Data Center shows very uneven load

Ah, I used Nable's markup and it seems to have eaten text somehow. Anyway,
here it is without formatting (much harder to read though)>

I have a very similar issue myself and would love to know what (if anything)
needs to be done (I'm using 1.1.6 at the moment). After stress-test (maximum
load), I had the following on my nodes (every IP is changed to the
corresponding fake number): 

c:\SERVERS\apache-cassandra-1.1.6\bin>nodetool -h 11.111.111.1 ring

This already shows uneven load despite the fact that nodes actually hold the
same amount of data (according to effective-ownership and application design
/ token values). 

However I then proceeded to drop the single keyspace that was on this
cluster and I got this: 

c:\SERVERS\apache-cassandra-1.1.6\bin>nodetool -h 11.111.111.1 ring
Starting NodeTool

keyspace.

Why 11.111.111.1 still has 700+ MB of data? I tried nodetool repair,
nodetool cleanup, and node restart (for 11.111.111.1) -- none of that helped
(it still had those 700+ MB of data). 

Here's info from the filesystem on that node:
