Hi, I'm running into this issue several times but still not able resolve kindly help me in this regard. I have written a crawler which will be keep running for several days after 4 days of continuous interaction of data base with my application system. Data base fails to responsed. I'm not able to figure where things all of a sudden can go wrong after 4 days of proper running. My configuration i have used hbase 0.96.2 single server. jdk 1.7
issue is this following error WARN [http-bio-8080-exec-4-SendThread(hadoop2:2181)] zookeeper.ClientCnxn (ClientCnxn.java:run(1089)) - Session 0x14da00e69e001ad for server null, unexpected error, closing socket connection and attempting reconnect java.net.ConnectException: Connection refused If this exception happens only solution i have is restart hbase that is not a viable solution because that will corrupt my system data.
