Summary: Performance gain if you use replace() instead of
replaceAll() for replacing patterns that do not use a regex
Key: HADOOP-16267
URL: https://issues.apache.org/jira/browse/HADOOP-16267
Project: Hadoop Common
Issue Type: Improvement
Reporter: bd2019us
Performance gain if you use replace() instead of replaceAll() for replacing
patterns that do not use a regex. This happens because replace() does not need
to compile the regex pattern like replaceAll() does.
