For RMD Stage we need Grouping Keys, Add one extra hard coded Column to each Input records in previous stage.
DUMMY=1
In RMD Stage,
HASH partition on DUMMY, Sort DESC on Salary
and select DUMMY as Key in properties tab.
"Duplicate to Retain"=First.
then you will get only Highest Salart only from RMD Stage
