Hi We have a 3 node secure Kafka Cluster ( https://kafka.apache.org/documentation/#security_ssl)
Recently, my producer client is receiving the below message. Can someone please help to understand the message and possible few pointers to fix debug and may be fix this issue. 18/03/15 14:37:23 INFO producer.ProducerConfig:180 ProducerConfig values: acks = all batch.size = 16384 block.on.buffer.full = false bootstrap.servers = [172.31.166.121:9093, 172.31.166.122:9093, 172.31.166.120:9093] buffer.memory = 33554432 client.id = compression.type = none connections.max.idle.ms = 540000 interceptor.classes = null key.serializer = class org.apache.kafka.common.serialization.StringSerializer linger.ms = 1 max.block.ms = 60000 max.in.flight.requests.per.connection = 50 max.request.size = 1048576 metadata.fetch.timeout.ms = 60000 metadata.max.age.ms = 300000 metric.reporters = [] metrics.num.samples = 2 metrics.sample.window.ms = 30000 partitioner.class = class org.apache.kafka.clients.producer.internals.DefaultPartitioner receive.buffer.bytes = 32768 reconnect.backoff.ms = 50 request.timeout.ms = 30000 retries = 3 retry.backoff.ms = 100 sasl.jaas.config = null sasl.kerberos.kinit.cmd = /usr/bin/kinit sasl.kerberos.min.time.before.relogin = 60000 sasl.kerberos.service.name = null sasl.kerberos.ticket.renew.jitter = 0.05 sasl.kerberos.ticket.renew.window.factor = 0.8 sasl.mechanism = GSSAPI security.protocol = SSL send.buffer.bytes = 131072 ssl.cipher.suites = null ssl.enabled.protocols = [TLSv1.2, TLSv1.1, TLSv1] ssl.endpoint.identification.algorithm = null ssl.key.password = [hidden] ssl.keymanager.algorithm = SunX509 ssl.keystore.location = /home/batman/ekc/keystore/keystore.jks ssl.keystore.password = [hidden] ssl.keystore.type = JKS ssl.protocol = TLS ssl.provider = null ssl.secure.random.implementation = null ssl.trustmanager.algorithm = PKIX ssl.truststore.location = /home/batman/ekc/keystore/truststore.jks ssl.truststore.password = [hidden] ssl.truststore.type = JKS timeout.ms = 30000 value.serializer = class org.apache.kafka.common.serialization.StringSerializer 18/03/15 14:37:23 INFO utils.AppInfoParser:83 Kafka version : 0.10.2.1 18/03/15 14:37:23 INFO utils.AppInfoParser:84 Kafka commitId : e89bffd6b2eff799 18/03/15 14:37:23 INFO ekc.Writer:78 Number of messages to send = 8 18/03/15 14:37:23 WARN network.SslTransportLayer:166 Failed to send SSL Close message java.io.IOException: Broken pipe at sun.nio.ch.FileDispatcherImpl.write0(Native Method) at sun.nio.ch.SocketDispatcher.write(SocketDispatcher.java:47) at sun.nio.ch.IOUtil.writeFromNativeBuffer(IOUtil.java:93) at sun.nio.ch.IOUtil.write(IOUtil.java:65) at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:471) at org.apache.kafka.common.network.SslTransportLayer.flush(SslTransportLayer.java:195) at org.apache.kafka.common.network.SslTransportLayer.close(SslTransportLayer.java:150) at org.apache.kafka.common.utils.Utils.closeAll(Utils.java:731) at org.apache.kafka.common.network.KafkaChannel.close(KafkaChannel.java:54) at org.apache.kafka.common.network.Selector.doClose(Selector.java:540) at org.apache.kafka.common.network.Selector.close(Selector.java:531) at org.apache.kafka.common.network.Selector.pollSelectionKeys(Selector.java:378) at org.apache.kafka.common.network.Selector.poll(Selector.java:303) at org.apache.kafka.clients.NetworkClient.poll(NetworkClient.java:349) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:225) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:126) at java.lang.Thread.run(Thread.java:748) 18/03/15 14:37:23 WARN network.SslTransportLayer:166 Failed to send SSL Close message java.io.IOException: Broken pipe at sun.nio.ch.FileDispatcherImpl.write0(Native Method) at sun.nio.ch.SocketDispatcher.write(SocketDispatcher.java:47) at sun.nio.ch.IOUtil.writeFromNativeBuffer(IOUtil.java:93) at sun.nio.ch.IOUtil.write(IOUtil.java:65) at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:471) at org.apache.kafka.common.network.SslTransportLayer.flush(SslTransportLayer.java:195) at org.apache.kafka.common.network.SslTransportLayer.close(SslTransportLayer.java:163) at org.apache.kafka.common.utils.Utils.closeAll(Utils.java:731) at org.apache.kafka.common.network.KafkaChannel.close(KafkaChannel.java:54) at org.apache.kafka.common.network.Selector.doClose(Selector.java:540) at org.apache.kafka.common.network.Selector.close(Selector.java:531) at org.apache.kafka.common.network.Selector.pollSelectionKeys(Selector.java:378) at org.apache.kafka.common.network.Selector.poll(Selector.java:303) at org.apache.kafka.clients.NetworkClient.poll(NetworkClient.java:349) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:225) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:126) at java.lang.Thread.run(Thread.java:748) R
