, and Flink is taking care of the rest. As far as I understood it, Hadoop has already all the utilities in place for getting and transferring the delegation tokens. Max Michels, another committer in our project has quite a good understanding of the details there. It would be great if you (Max) could

Hi Amit, Nice to hear you're interested in Flink. The first thing you could do is run the provided examples. Next, you could try to implement a simple Flink job yourself. Besides the How to contribute guide, take a look at the material page [1], the Flink blog [2], and the Data Artisans blog [3].

This is a must-have. I would like to take a look at the automatic doc build infrastructure next week. Basically we have to write some buildbot rules which issue a build and upload of the docs on a daily basis. On Wed, Feb 18, 2015 at 4:53 PM, Robert Metzger rmetz...@apache.org wrote: Thats

Re: Design Question in Expression API

2015-02-03 Thread Max Michels
If we want to have a tight integration with our existing API we have to hide the results of the expressions behind a wrapper. This enables us to change the internal implementation at any time and support future Flink API changes and features. +1 for not directly exposing the results as a row

Re: Task manager memory configuration with intermediate results

+1 The static memory assignment of the network buffer tool caused some problems for users in the past. Ultimately, dynamic memory management would be desirable. Until then, let's remove the absolute value configuration for the network buffers and introduce a parameter to divide the heap memory

Re: Question about Commit Policy

Let me clarify my suggestion: Let's put mandatory tags in the second line of the commit message. That way, they can be filtered using git log --grep=TAG and do not take away the first line's 80 characters. On Wed, Jan 28, 2015 at 3:37 AM, Henry Saputra henry.sapu...@gmail.com wrote: Just found

Let's make it clear that count/collection type of actions execute the plan up till that point (including the data sinks). From a user perspective, this seems most logic to me. The user might even rely on the data generated by the sinks. On Mon, Jan 19, 2015 at 11:46 AM, Fabian Hueske

Re: Master not building and how to notice it faster in the future

2015-01-21 Thread Max Michels
Hi Robert, I like your solution using Travis and Google App Engine. However, I think there's a much simpler solution which can prevent commiters from pushing not even compiling or test-failing code to the master in the first place. Commiters could simply install a git pre-push hook in their git
