Description

I don't see any reason why we should keep this message:

client.HConnectionManager$HConnectionImplementation: Cache hit for row <0003706355> in tableName TestTable: location server sv2borg176:60020, location region name TestTable,0003706355,1302908760305.7ac9fae7facc8a69330340f1c3977339.

It happens only when we are looking for a region in the HCM cache and the row key we use is the start key of that region.

I don't just find it useless, also it litters our thrift logs.
