I witnessed the same behavior as reported by Edward and James. Removing the host from its own seed list does not solve the problem. Removing it from config of all nodes and restarting each, then restarting the failed node worked. Ron On Sep 12, 2012, at 4:42 PM, Edward Sargisson wrote

ColumnFamily per Index?

2011-09-23 Thread Ron Siemens
. I can just create a ColumnFamily per field being indexed. I can now easily access and update the indexes for a particular field. I'm wondering if anyone has also contemplated this Column-Family-per-Index-Field option or is using it, and has any thoughts or critique regarding it. Ron
