[jira] [Commented] (MAPREDUCE-5993) native-task: simplify/remove dead code

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5993?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14071345#comment-14071345 ] 

Todd Lipcon commented on MAPREDUCE-5993:
----------------------------------------

Another area for simplification: ByteBufferDataReader/Writer seem to have manual implementations of UTF8 encode/decode, but they aren't perf sensitive, best I can tell. We should just use the existing Java facilities for this to remove some code.

> The native task code has a bunch of code in it which isn't related to the map output collector. I suspect much if this is dead code. Let's remove it before we merge, so that the amount of code we have to maintain going forward is more limited.
