Hello! We have a real-time streaming workflow that has been running for about 2.5 weeks.
Then, we began to get the exception below from taskmanagers (random) since yesterday, and the job began to fail/restart every hour or so. The job does recover after each restart, but sometimes it takes more time to recover than allowed in our environment. On a few occasions, it took more than a few restarts to fully recover. Can you provide some insight into what this error means and also what we can do to prevent this in future? Thank you! +++ ERROR org.apache.flink.runtime.io.network.netty.PartitionRequestQueue - Encountered error while consuming partitions java.io.IOException: Connection reset by peer at sun.nio.ch.FileDispatcherImpl.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:39) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:223) at sun.nio.ch.IOUtil.read(IOUtil.java:192) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:379) at org.apache.flink.shaded.netty4.io .netty.buffer.PooledByteBuf.setBytes(PooledByteBuf.java:247) at org.apache.flink.shaded.netty4.io .netty.buffer.AbstractByteBuf.writeBytes(AbstractByteBuf.java:1140) at org.apache.flink.shaded.netty4.io.netty.channel.socket.nio.NioSocketChannel.doReadBytes(NioSocketChannel.java:347) at org.apache.flink.shaded.netty4.io.netty.channel.nio.AbstractNioByteChannel$NioByteUnsafe.read(AbstractNioByteChannel.java:148) at org.apache.flink.shaded.netty4.io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:697) at org.apache.flink.shaded.netty4.io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:632) at org.apache.flink.shaded.netty4.io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:549) at org.apache.flink.shaded.netty4.io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:511) at org.apache.flink.shaded.netty4.io .netty.util.concurrent.SingleThreadEventExecutor$5.run(SingleThreadEventExecutor.java:918) at org.apache.flink.shaded.netty4.io .netty.util.internal.ThreadExecutorMap$2.run(ThreadExecutorMap.java:74) at java.lang.Thread.run(Thread.java:748) ______________________________________________________________________ The information contained in this e-mail is confidential and/or proprietary to Capital One and/or its affiliates and may only be used solely in performance of work or services for Capital One.
