Hadoop MapReduce job I/O Exception due to premature EOF from inputStream
问题 I ran a MapReduce program using the command hadoop jar <jar> [mainClass] path/to/input path/to/output . However, my job was hanging at: INFO mapreduce.Job: map 100% reduce 29% . Much later, I terminated and checked the datanode log (I am running in pseudo-distributed mode). It contained the following exception: java.io.IOException: Premature EOF from inputStream at org.apache.hadoop.io.IOUtils.readFully(IOUtils.java:201) at org.apache.hadoop.hdfs.protocol.datatransfer.PacketReceiver
