Description
I encountered an Exception when communicating between two nodes using load-balanced connections. Within 2 minutes, I had geneated 2.5 GB of error logs, all of the pattern:
2019-10-09 14:36:35,091 ERROR [Load-Balance Server Thread-17] o.a.n.c.q.c.s.ConnectionLoadBalanceServer Failed to communicate with Peer localhost/127.0.0.1:61671 java.net.SocketException: Socket is closed at sun.security.ssl.SSLSocketImpl.checkEOF(SSLSocketImpl.java:1532) at sun.security.ssl.AppInputStream.read(AppInputStream.java:95) at java.io.BufferedInputStream.fill(BufferedInputStream.java:246) at java.io.BufferedInputStream.read(BufferedInputStream.java:265) at org.apache.nifi.controller.queue.clustered.server.StandardLoadBalanceProtocol.negotiateProtocolVersion(StandardLoadBalanceProtocol.java:143) at org.apache.nifi.controller.queue.clustered.server.StandardLoadBalanceProtocol.receiveFlowFiles(StandardLoadBalanceProtocol.java:122) at org.apache.nifi.controller.queue.clustered.server.ConnectionLoadBalanceServer$CommunicateAction.run(ConnectionLoadBalanceServer.java:152) at java.lang.Thread.run(Thread.java:745) 2019-10-09 14:36:35,091 ERROR [Load-Balance Server Thread-5] o.a.n.c.q.c.s.ConnectionLoadBalanceServer Failed to communicate with Peer localhost/127.0.0.1:61644 java.net.SocketException: Socket is closed at sun.security.ssl.SSLSocketImpl.checkEOF(SSLSocketImpl.java:1532) at sun.security.ssl.AppInputStream.read(AppInputStream.java:95) at java.io.BufferedInputStream.fill(BufferedInputStream.java:246) at java.io.BufferedInputStream.read(BufferedInputStream.java:265) at org.apache.nifi.controller.queue.clustered.server.StandardLoadBalanceProtocol.negotiateProtocolVersion(StandardLoadBalanceProtocol.java:143) at org.apache.nifi.controller.queue.clustered.server.StandardLoadBalanceProtocol.receiveFlowFiles(StandardLoadBalanceProtocol.java:122) at org.apache.nifi.controller.queue.clustered.server.ConnectionLoadBalanceServer$CommunicateAction.run(ConnectionLoadBalanceServer.java:152) at java.lang.Thread.run(Thread.java:745)
