We also noticed this after upgrading from 1.1.3 to 1.1.6. Every node runs a 0 row hinted handoff every 10 minutes. N-1 nodes hint to the same node, while that node hints to another node.

Hi,

I have the exact same problem with 1.1.6. HintsColumnFamily consists of one row (Rowkey 00, nothing more). The "problem" started after upgrading from 1.1.4 to 1.1.6. Every ten minutes HintedHandoffManager starts and finishes after sending "0 rows".

.vegard,
