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

             Summary: refactor ref guide text to remove EOM versions
                 Key: HBASE-20757
                 URL: https://issues.apache.org/jira/browse/HBASE-20757
             Project: HBase
          Issue Type: Task
          Components: community, documentation
            Reporter: Sean Busbey


we still have references in the guide going back as far as version 0.90. remove them, keep any points that are still relevant to current versions.

e.g. this bit should just be removed:

{code}
NOTE: online schema changes are supported in the 0.92.x codebase, but the 0.90.x codebase requires the table to be disabled.
{code}

but this one needs to be rewritten:

{code}
The recommended approach is to let HBase add its dependency jars and use `HADOOP_CLASSPATH` or `-libjars`.

Since HBase `0.90.x`, HBase adds its dependency JARs to the job configuration itself.
The dependencies only need to be available on the local `CLASSPATH` and from here they'll be picked
up and bundled into the fat job jar deployed to the MapReduce cluster. A basic trick just passes
{code}

to essentially just say "HBase adds its dependency jars to the job configuration itself."
