FLUME-3144. Improve Log4jAppender's performance by allowing logging collection of messages `Log4jAppender` treats `Collection` messages as a special case making it possible to log collection of events in one Log4j log call. The appender sends these events to the receiving Flume instance as one batch with the `rpcClient.appendBatch()` method. New tests added: - logging of a collection of multiple strings, expect one `appendBatch()` call. - logging one string, expect one `append()` call. - logging of a singleton collection of a string, expect one `append()` call. - logging of an empty collection, expect that neither `append()` nor `appendBatch()` was called. - logging of a `String` and an arbitrary object in one collection with `AvroReflectionEnabled` set to `true` - logging of a `String` and an arbitrary object in one collection with `AvroReflectionEnabled` set to `false` You can merge this pull request into a Git repository by running: $ git pull https://github.com/adenes/flume FLUME-3144 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/flume/pull/151.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #151 ---- commit ba4a9a9793104be715d451cc06c42ac73a77e00e Author: Denes Arvay <de...@apache.org> Date: 2017-08-11T14:22:04Z FLUME-3144.
