Date Sat, 29 Oct 2016 00:32:58 GMT
Duo Zhang created HBASE-16968:

             Summary: Refactor FanOutOneBlockAsyncDFSOutput
                 Key: HBASE-16968
                 URL: https://issues.apache.org/jira/browse/HBASE-16968
             Project: HBase
          Issue Type: Sub-task
          Components: io, wal
    Affects Versions: 2.0.0
            Reporter: Duo Zhang
             Fix For: 2.0.0

As we have moved to jdk8, and dropped the support of hadoop-2.4.x and hadoop-2.5.x on master,
we could use CompletableFuture instead of CompletionHandler to make the code more clear, and
also remove the support of hadoop-2.4.x and hadoop-2.5.x to remove lots of the reflection
