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

ERROR hdfs.DFSClient ( - Failed to close inode 4290642291 java.nio.channels.ClosedByInterruptException at java.nio.channels.spi.AbstractInterruptibleChannel.end( at at$Writer.performIO( at at at at at at org.apache.hadoop.hdfs.DFSPacket.writeTo( at org.apache.hadoop.hdfs.DFSOutputStream$ 2019-02-11 17:14:33,789 INFO namenode.NameNode ( - SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down NameNode at ************************************************************/ hadoop-hdfs-namenode-xx-xxxx-xxxx.log lines 1009951-1009982/1009982 (END) packet_write_wait: Connection to port 22: Broken pipe
