PJ Fanning created HADOOP-19134:
-----------------------------------
Summary: use StringBuilder instead of StringBuffer
Key: HADOOP-19134
URL: https://issues.apache.org/jira/browse/HADOOP-19134
Project: Hadoop Common
Issue Type: Improvement
Reporter: PJ Fanning
StringBuilder is basically the same as StringBuffer but doesn't use
synchronized. String appending rarely needs locking like this.
There are some public and package private APIs that use StringBuffers as input
or return types - I have left these alone for compatibility reasons.
