Hi, My environment is Windows 64bit, Spark + YARN. I had a job that takes a long time. It starts well, but it ended with below exception:
15/03/25 12:39:09 WARN server.TransportChannelHandler: Exception in connection from headnode0.xshe3539-hadoop-sydney.q10.internal.cloudapp.net/100.72.68.34:58507 java.io.IOException: An existing connection was forcibly closed by the remote host at sun.nio.ch.SocketDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:43) 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 io.netty.buffer.PooledUnsafeDirectByteBuf.setBytes(PooledUnsafeDirectByteBuf.java:311) at io.netty.buffer.AbstractByteBuf.writeBytes(AbstractByteBuf.java:881) at io.netty.channel.socket.nio.NioSocketChannel.doReadBytes(NioSocketChannel.java:225) at io.netty.channel.nio.AbstractNioByteChannel$NioByteUnsafe.read(AbstractNioByteChannel.java:119) at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:511) at io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:468) at io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:382) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:354) at io.netty.util.concurrent.SingleThreadEventExecutor$2.run(SingleThreadEventExecutor.java:116) at java.lang.Thread.run(Thread.java:745) 15/03/25 12:39:09 ERROR executor.CoarseGrainedExecutorBackend: Driver Disassociated [akka.tcp:// sparkexecu...@workernode0.xshe3539-hadoop-sydney.q10.internal.cloudapp.net:65469] -> [akka.tcp:// sparkdri...@headnode0.xshe3539-hadoop-sydney.q10.internal.cloudapp.net:58467] disassociated!

Reason is: [Disassociated]. Interestingly, the job is shown as Succeeded in the RM. I checked the application log, it is miles long, and this is the only exception I found. And it is no very useful to help me pin point the problem. Any idea what would be the cause?
