Summary: RBF : Reuse ugi string in ConnectionID
Key: HDFS-15094
URL: https://issues.apache.org/jira/browse/HDFS-15094
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Ayush Saxena
Assignee: Ayush Saxena
The connectionID 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.
