How can we use nodetool to find unbalance in cluster ?

I need to know if we can find if there is an unbalance in the cluster using the nodetool provided with cassandra 1.1.6.

Solution

  • Use nodetool ring and pay attention to the Owns column.

    lyubent:bin lyubentodorov$ ./nodetool ring

    On a side note, if you are starting out with C* you should target more up-to-date versions.
