             Summary: Usage of incorrect regex range A-z
                 Key: HADOOP-17518
                 URL: https://issues.apache.org/jira/browse/HADOOP-17518
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Marcono1234


There are two cases where the regex {{A-z}} is used. I assume that is a typo (and should be {{A-Z}} because {{A-z}} matches:
- {{A-Z}}
- {{\[}}, {{\}}, {{\]}}, {{^}}, {{_}}, {{`}}
- {{a-z}}
