Fuud created CASSANDRA-13456:
--------------------------------
Summary: Needs better logging for timeout/failures
Key: CASSANDRA-13456
URL: https://issues.apache.org/jira/browse/CASSANDRA-13456
Project: Cassandra
Issue Type: Bug
Reporter: Fuud
When read was failed due to timeout, Cassandra reports in logs "Timeout;
reveived 1 of 3 responses". Same information is passed to clients.
But this information is not enoght to get list of slow nodes.
Better to have detailed message in debug log:
"Timeout; reveived 1 of 4 responses. Requested but not responded node: [<ip1>,
<ip2>], Failed nodes: [<ip3>]"
I implemented such behavior by patching ReadCallback,
AbstractWriteResponseHandler, DatacenterSyncWriteResponseHandler and
WriteResponseHandler. It handles all cases except Paxos.
But I want to implement solid solution that handle all cases in same way.
But before I will start I want to know: are there any objections against such
logging?
