             Summary: Help Phoenix better identify itself when something goes wrong on a cluster
                 Key: HBASE-20692
                 URL: https://issues.apache.org/jira/browse/HBASE-20692
             Project: HBase
          Issue Type: Wish
          Components: community
    Affects Versions: 2.0.0
            Reporter: Sean Busbey


User list question about a failing 2.0.0 test cluster came in[1], turned out to be Phoenix installed but missing from the classpath. Problem area wasn't immediately obvious because the ClassNotFoundException appeared to be for an HBase class: org.apache.hadoop.hbase.regionserver.wal.IndexedWALEditCodec.

Checking on recent-ish phoenix, they have a bunch of classes in org.apache.hadoop.hbase[2]. Presumably to circumvent package-protected access restrictions, but I didn't check.

Should come up with some ways to make it more obvious when our shared users need to talk with them. this jira's a place to collect some suggestions once folks have a chance to see why phoenix is in our package space in the first place. Once we have something concrete to propose we can take the suggestions over to dev@phoenix.
