to 0 nodes instead of minReplication (=1)报错怎么处理

Error:map.xml could only be replicated to 0 nodes instead of minReplication (=1)

hive执行一条sql语句,然后map,reduce做完了,写数据挂了

错误:

java.lang.RuntimeException: Error caching map.xml: org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /tmp/hive/root/675fa67b-59c3-4de7-99a9-3f5be9f6685c /hive_2016-07-19_16-11-06_796_8611429774960723114-1/-mr-10013/f1b1cc9d-19ef-448c-8b9d-3e48129c7fec/map.xml could only be replicated to 0 nodes instead of minReplication (=1). There are 3 datanode(s) running and no node(s) are excluded in this operation.
