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 code.
