## ** cdh中hdfs的namenode的datenode的cluster Id不一致导致hdfs启动失败** ##

手动修改namenode中的VERSION文件，我的这个文件存在两个，路径分别为/data1/dfs/nn/current和/data10/dfs/nn/current，分别按照以下步骤修改：

cd /data10/dfs/nn/current

vim VERSION

#Tue Feb 26 17:26:34 CST 2019
    namespaceID=689934995
    clusterID=hacl-pepstack-com
    cTime=0
    storageType=NAME_NODE
    blockpoolID=BP-165196685-10.142.149.248-1551173194257
    layoutVersion=-60

将VERSION文件中namespaceID=689934995改为DATANODE日志中报的datanode clusterID = hacl-pepstack-com，然后重新启动namenode就好了。

我的datenode的日志文件路径是/var/log/hadoop-hdfs/hadoop-cmf-hdfs-DATANODE-A5-401-NF5280M4-2017-247.BIGDATA.CHINATELECOM.CN.log.out，datenode的报错为：
