Ayush Saxena updated HDFS-15094:
--------------------------------
Description:
The connectionPoolID Hash Code and equals contains ugi.toString(), These
methods are used as part of getConnection() in ConnectionManager as part of
every call.
The ugi.toString() eats up considerable amount of time, the Hash Calculation
itself is ~10 percent of the total time of the call. And even more for the
equals method.
