-------------------------------------

             Summary: Allow dot and hyphen in Profiler's URL
                 Key: HBASE-23663
                 URL: https://issues.apache.org/jira/browse/HBASE-23663
             Project: HBase
          Issue Type: Bug
          Components: profiler
    Affects Versions: 2.1.5, 2.2.0, 3.0.0, 2.3.0
            Reporter: Peter Somogyi
            Assignee: Peter Somogyi


ProfileOutputServlet sanitizes the input URL but fails when the query string contains dot or hyphen. These are valid characters for the hostname.

Example URL part:

/prof-output/async-prof-pid-122466-cpu-1.svg?host=myhost-1.example.com&port=16010 

In this case the user gets the following error message:
{noformat}
HTTP ERROR: 500
Problem accessing /prof-output/async-prof-pid-122466-cpu-1.svg. Reason:
    java.lang.RuntimeException: Non-alphanumeric data found in input, aborting.
