Subject Why data is not even distributed.
Date Thu, 04 Oct 2012 00:39:29 GMT
Hello, everybody!

I'm observing very strange behavior. I have 3 node cluster with
ByteOrderPartitioner. (I run 1.1.5)
I created a key space with replication factor of 1.
Then I created one column family and populated it with random data.
I use UUID as a row key, and Integer as a column name.
Row keys were generated as

UUID uuid = UUID.randomUUID();

I populated about 100000 rows with 100 column each.

I would expect equal load on each node, but the result is totally
different. This is what nodetool gives me:

Address         DC          Rack        Status State   Load

one node (127.0.0.3) is almost empty.
Any ideas what is wrong?


Thank you,
