问题
I am trying to install Hadoop(3.1.2) on Windows-10, but data node and node manager shuts down.
I have tried downloading and placing the winutils.exe and hadoop.dll files under bin directory. I have also tried changing the permissions of the files and running as an administrator. But it didn't fix the error
Datanode shutdown error

I know this is too much to ask because of the cumbersome task of hadoop installation but any help would be greatly appreciated
回答1:
I overwrote all the files under bin directory with these files and everything started working as expected
回答2:
In C:\BigData\hadoop-2.9.1\etc\hadoop''' directry openhdfs-site.xml``` file and set namenode and datanode location as
/BigData/hadoop-2.9.1/data/namenode
/BigData/hadoop-2.9.1/data/datanode
Then
- Open cmd as administrator.
- Type and run
stop-all.cmd hadoop namenode –formatstart-all.cmd
