Dick King updated MAPREDUCE-1309:
---------------------------------
Attachment: demuxer-plus-concatenated-files--2009-12-21.patch
This patch implements a universal gridmix3/mumak trace generator.
It differs from previous versions of rumen in three ways:
1: The mainclass is o.a.h.tools.rumen.Driver
2: This tool is specialized to make traces. Future statisticsengines will be
trace-based
3: The argument list is more austere. There are three or more arguments:
3a: the trace output, a {{Path}} , compressed or not
3b: the topology output, again a {{Path}} , again compressed or not
3c: any number of {{Path}} names, each of which can be compressed or not, and
each of which can be a config.xml file, a job tracker log [ {{Driver}}
determines the version ], or a directory filled with such files.
> 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].
