Trying to add more space to HDFS, I tried to follow available instructions.
The problem is that while dfs.datanode.data.dir suppose to be comma-delimited value, Ambari notify it is wrong.
Without the comma, or with semicolon, it seems to pass validation - but I rather not try to save those changes without telling what it will do.
Any help would be appreciated.
Can you specify like this -
Please do not specify it on new like via pressing "Enter".
Let me know if it works.
