Summary: Optimize ByteString conversions in PBHelper
Key: HDFS-13601
URL: https://issues.apache.org/jira/browse/HDFS-13601
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.9.1, 3.1.0
Reporter: Andrew Wang
Assignee: Andrew Wang
While doing some profiling of the NN with JMC, I saw a lot of time being spent
on String->ByteString conversions. These are often the same strings being
converted over and over again, meaning there's room for optimization.
