[jira] [Created] (PHOENIX-4408) Figure out Hadoop version compatibility

Josh Elser created PHOENIX-4408:
-----------------------------------

             Summary: Figure out Hadoop version compatibility
                 Key: PHOENIX-4408
                 URL: https://issues.apache.org/jira/browse/PHOENIX-4408
             Project: Phoenix
          Issue Type: Sub-task
            Reporter: Josh Elser
            Priority: Blocker
             Fix For: 5.0.0


The 5.x-HBase-2.0 branch is presently incompatible with both Hadoop 2.7 and Hadoop 3.0.

This stems from PhoenixMetricsSink and LoggingSink both of which extend MetricsSink from Hadoop. Hadoop leaks a commons-configuration class into a method signature and changes the dependency across versions.

This makes it extremely annoying to work around downstream (we would have to create multiple maven modules to shim around this). We should figure out what compatibility we want to have.  Post PHOENIX-4405, it's only Hadoop3.
