hadoop word stats not uploading

The reason may be that after I start the dfs and yarn service due to my frequent formatting, resulting in my slave01 and slave02 inside the hadoop/hdfs/data/current/VERSION file in the clusterID is not consistent with the master, and enter jps command, my slave01 and slave02 datanode is not started. Solution: Delete the folder hadoop/hdfs/data in slave01 and slave02, then create a new data file, then format it in the bin path, and finally restart the dfs and yarn services.
