i tried previously to set the ZK connection and the session time out to more than 30mn (via storm.yaml). But within less than 1mn, i have the following exception
45431 [main-SendThread(localhost:2000)] INFO org.apache.storm.zookeeper.ClientCnxn - Client session timed out, have not heard from server in 27264ms for sessionid 0x14f6956c7ba0003, closing socket connection and attempting reconnect 45438 [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2000] WARN org.apache.storm.zookeeper.server.NIOServerCnxn - caught end of stream exception org.apache.storm.zookeeper.server.ServerCnxn$EndOfStreamException: Unable to read additional data from client sessionid 0x14f6956c7ba0005, likely client has closed socket i noticed (in the log) that the ZK session timeout cannot be changed : i have the following : org.apache.storm.zookeeper.server.ZooKeeperServer - Created server with tickTime 2000 minSessionTimeout 4000 maxSessionTimeout 40000 so maybe the Client session is timed out because of the ZK « small » tickTime. I have a doubt that the changes i made are not really considered by storm. Thanks, Lina > Le 27 août 2015 à 10:53, Matthias J.
