Jason Harvey updated CASSANDRA-6546:
------------------------------------
Description:
-Disabling and then re-enabling thrift resulted in this stat reporting double
the number of connected sockets on the service.
Alternatively, if the metric is accurate, then disabling and then re-enabling
thrift may be resulting in a bunch of unused FDs?
Reproducing is easy. Have a handful of thrift clients, disablethrift, wait a
few minutes, re-enable thrift, have your client apps reconnect, then compare
actual connected sockets (via netstat or lsof or what have you) to the value
from this MBean (
org.apache.cassandra.metrics:type=Client,name=connectedThriftClients ).-
