Subject [jira] [Commented] (FLINK-838) GSoC Summer Project: Implement full Hadoop Compatibility Layer for Stratosphere
Date Wed, 13 Aug 2014 22:48:11 GMT

    [ https://issues.apache.org/jira/browse/FLINK-838?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14096255#comment-14096255
] 

Fabian Hueske commented on FLINK-838:
-------------------------------------

I just updated my branch. It is rebased to the current master. I implemented a HadoopJobOperation,
which performs a Hadoop Map and Reduce such that the new operators are not accessible through
the regular API other than using the HadoopJobOperation. I also generalized the code in java-api,
compiler, and runtime a bit. It is not very nice right now, but can be improved once the explicit
partitioning is added to the API (something more general than FLINK-653).

The code is not perfect yet, but a good starting point to add more functionality.
Artem: Would you pick up my branch and add your latest changes and the other features you
were working on to it?

> This is a meta issue for tracking @atsikiridis progress with implementing a full Hadoop
Compatibliltiy Layer for Stratosphere.
> Some documentation can be found in the Wiki: https://github.com/stratosphere/stratosphere/wiki/%5BGSoC-14%5D-A-Hadoop-abstraction-layer-for-Stratosphere-(Project-Map-and-Notes)
> As well as the project proposal: https://github.com/stratosphere/stratosphere/wiki/GSoC-2014-Project-Proposal-Draft-by-Artem-Tsikiridis
> Most importantly, there is the following **schedule**:
> *19 May - 27 June (Midterm)*
> 1) Work on the Hadoop tasks, their Context and the mapping of Hadoop's Configuration
to the one of Stratosphere. By successfully bridging the Hadoop tasks with Stratosphere, we
already cover the most basic Hadoop Jobs. This can be determined by running some popular Hadoop
examples on Stratosphere (e.g. WordCount, k-means, join) (4 - 5 weeks)
> 2) Understand how the running of these jobs works (e.g. command line interface) for the
wrapper. Implement how will the user run them. (1 - 2 weeks).
> *27 June - 11 August*
> 1) Continue wrapping more "advanced" Hadoop Interfaces (Comparators, Partitioners, Distributed
Cache etc.) There are quite a few interfaces and it will be a challenge to support all of
them. (5 full weeks)
> 2) Profiling of the application and optimizations (if applicable)
> *11 August - 18 August*
> Write documentation on code, write a README with care and add more unit-tests. (1 week)
