> GlobPattern regex library has performance issues with wildcard characters

>
> Key: HADOOP-12436
> URL: https://issues.apache.org/jira/browse/HADOOP-12436
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 2.2.0, 2.7.1
> Reporter: Matthew Paduano
> Assignee: Matthew Paduano
> Attachments: HADOOP-12436.01.patch, HADOOP-12436.02.patch,

>
> java.util.regex classes have performance problems with certain wildcard
> patterns. Namely, consecutive * characters in a file name (not properly
> escaped as literals) will cause commands such as "hadoop fs -ls
> file******name" to consume 100% CPU and probably never return in a reasonable
> time (time scales with number of *'s).
> Here is an example:
> {noformat}
> hadoop fs -touchz
> /user/mattp/job_1429571161900_4222-1430338332599-tda%2D%2D\\\+\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\*\\\+\\\+\\\+...%270%27%28Stage-1430338580443-39-2000-SUCCEEDED-production%2Dhigh-1430338340360.jhist

> Not every string of *'s causes this, but the above filename reproduces this
> reliably.
