> ------------------------------------------------------------------------

> Key: HADOOP-6490
> URL: https://issues.apache.org/jira/browse/HADOOP-6490
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.20.1
> Reporter: Zheng Shao
> Priority: Minor
> Labels: newbie
>
> in our environment, we are seeing that the JobClient is going out of memory
> because Path.normalizePath(String) is called several tens of thousands of
> times, and each time it calls "String.replace" twice.
> java.lang.String.replace compiles a regex to do the job which is very costly.
> We should use org.apache.commons.lang.StringUtils.replace which is much
> faster and consumes almost no extra memory.
