Please update BigDataClass.org source code on Github

Anirvan BASU
Hello,

Has anyone used recently the source code on BigDataClass.org (using TF-IDF) ?
Specifically, with Flink 0.6 or 0.7 ?

We modified the programme source code in Java (also dependencies using the new pom.xml from quickstart, etc).
with the domain name changes : eu.stratosphere --> org.apache.flink

Also,
some of the common functions have also changed locations (e.g.
eu.stratosphere.api.java.functions.FlatMapFunction --> org.apache.flink.api.java.common.functions.FlatMapFunction )

We tried to compile and none of the source code compiles correctly.

We received huge amount of errors :-((
Swimming in the dark - really helpless !

Could anyone please update the src and the pom.xml files on github to conform with flink 0.7 or even 0.6 ?

Below is the list of some of the errors.

Thanks in advance,
Anirvan

Re: Please update BigDataClass.org source code on Github

Kostas Tzoumas
That's true, that website has not been maintained for a while. That website is not part of Apache Flink, so this mailing list might not be the best place to ask for help. Perhaps someone that is reading this will pick it up though. 

It looks like you need to forward-port the job to the current Java API (among a few other Java errors). There have been more changes to the API between 0.5 and 0.7 than simple renaming of the packages.

Hello,

Has anyone used recently the source code on BigDataClass.org (using TF-IDF) ?
Specifically, with Flink 0.6 or 0.7 ?

We modified the programme source code in Java (also dependencies using the new pom.xml from quickstart, etc).
with the domain name changes : eu.stratosphere --> org.apache.flink

Also,
some of the common functions have also changed locations (e.g.
eu.stratosphere.api.java.functions.FlatMapFunction --> org.apache.flink.api.java.common.functions.FlatMapFunction )

We tried to compile and none of the source code compiles correctly.

We received huge amount of errors :-((
Swimming in the dark - really helpless !

Could anyone please update the src and the pom.xml files on github to conform with flink 0.7 or even 0.6 ?

Below is the list of some of the errors.

Thanks in advance,
Anirvan
