Hadoop Namenode不能启动 dfs/name is in an inconsistent
前段时间自己的本机上搭的Hadoop环境（按文档的伪分布式），第一天还一切正常，后来发现每次重新开机以后都不能正常启动，
在start-dfs.sh之后jps一下发现namenode不能正常启动，按提示找到logs目录下namenode的启动log发现如下异常
org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /tmp/hadoop-javoft/dfs/name is in an inconsistent state: storage di rectory does not exist or is not accessible.
