Our NameNode is getting down quite frequently. Upon checking logs, found below exception.

ERROR hdfs.DFSClient (DFSClient.java:closeAllFilesBeingWritten(959)) - Failed to close inode 4290642291 java.nio.channels.ClosedByInterruptException at java.nio.channels.spi.AbstractInterruptibleChannel.end(AbstractInterruptibleChannel.java:202) at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:478) at org.apache.hadoop.net.SocketOutputStream$Writer.performIO(SocketOutputStream.java:63) at org.apache.hadoop.net.SocketIOWithTimeout.doIO(SocketIOWithTimeout.java:142) at org.apache.hadoop.net.SocketOutputStream.write(SocketOutputStream.java:159) at org.apache.hadoop.net.SocketOutputStream.write(SocketOutputStream.java:117) at java.io.BufferedOutputStream.write(BufferedOutputStream.java:122) at java.io.DataOutputStream.write(DataOutputStream.java:107) at org.apache.hadoop.hdfs.DFSPacket.writeTo(DFSPacket.java:176) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:623) 2019-02-11 17:14:33,789 INFO namenode.NameNode (LogAdapter.java:info(47)) - SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down NameNode at xx-xxxx-xxxx.xxxx.xxx/xx.xxx.xxx.xx ************************************************************/ hadoop-hdfs-namenode-xx-xxxx-xxxx.log lines 1009951-1009982/1009982 (END) packet_write_wait: Connection to xx.xxx.xxx.xx port 22: Broken pipe

Would be helpful on any suggestions.

Thanks!
