[jira] [Created] (HADOOP-14862) Metrics for AdlFileSystem

John Zhuge created HADOOP-14862:
-----------------------------------

             Summary: Metrics for AdlFileSystem
                 Key: HADOOP-14862
                 URL: https://issues.apache.org/jira/browse/HADOOP-14862
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/adl
    Affects Versions: 2.8.0
            Reporter: John Zhuge


Add a Metrics2 source {{AdlFileSystemInstrumentation}} for {{AdlFileSystem}}.

Consider per-thread statistics data if possible. Atomic variables are not totally free in multi-core arch. Don't think Java can do per-cpu data structure.
