Dick King commented on MAPREDUCE-1309:
--------------------------------------
The new javac warnings are uses of deprecated API in the test cases. It's
necessary at this time.
The javadoc warnings look like this:
{noformat}
[exec] [javadoc] Building tree for all the packages and classes...
[exec] [javadoc]
/grid/0/hudson/hudson-slave/workspace/Mapreduce-Patch-h6.grid.sp2.yahoo.net/trunk/src/java/org/apache/hadoop/mapred
/FileInputFormat.java:323: warning - @param
argument "inputs" is not a parameter name.
[exec] [javadoc]
/grid/0/hudson/hudson-slave/workspace/Mapreduce-Patch-h6.grid.sp2.yahoo.net/trunk/src/java/org/apache/hadoop/mapreduce/lib/input
/FileInputFormat.java:356: warning - @param
argument "inputs" is not a parameter name.
{noformat}
[I changed the formatting on the console printout excerpt to make it render
better]
These are warnings that have nothing to do with this patch.
> I want to change the rumen job trace generator to use a more modular internal
> structure, to allow for more input log formats

> There are two orthogonal questions to answer when processing a job tracker
> log: how will the logs and the xml configuration files be packaged, and in
> which release of hadoop map/reduce were the logs generated? The existing
> rumen only has a couple of answers to this question. The new engine will
> handle three answers to the version question: 0.18, 0.20 and current, and two
> answers to the packaging question: separate files with names derived from the
> job ID, and concatenated files with a header between sections [used for
> easier file interchange].
