[jira] [Created] (HBASE-25149) Profiling servlet stuck in a loop when output directory does not exist

Nick Dimiduk created HBASE-25149:
------------------------------------

             Summary: Profiling servlet stuck in a loop when output directory does not exist
                 Key: HBASE-25149
                 URL: https://issues.apache.org/jira/browse/HBASE-25149
             Project: HBase
          Issue Type: Bug
          Components: Performance
    Affects Versions: 2.3.0
            Reporter: Nick Dimiduk


When the profiling servlet runs async-profiler when the output path ({{/tmp/prof-output}} doesn't exist or isn't writable by the {{hbase}} process, it will sit in a refresh loop indefinitely.  The servlet should check that the output path is writable, or even make an attempt to create the output directory, and inform the user of the situation, rather than attempting and silently failing to generate the flame graph.
