Incompatible name space Id error.its because dat u might have formatted the
namenode but data nodes folder is still have the same I'd.
What is the value of the following property
dfs. Data.dir
dfs. name.dir
hadoop.tmp.dir
The value of these properties is directory on local file system
Solution i
You reformatted your NameNode at some point, but likely failed to also
clear out the DN data directories, which would not auto-wipe
themselves.
Clear the contents of /app/hadoop/tmp/dfs/data at the DN and it should
start up the next time you invoke it.
