Steve, Thank you for the answer. How Hortonworks deal with this problem internally ? You have Spark 1.3.1 in HDP 2.3. Is it compilled with Jackson 2.2.3 ? Regards, Maciek 2016-01-13 18:00 GMT+01:00 Steve Loughran : > >> On 13 Jan 2016, at 03:23, Maciej Bryński

Hi, What is the best IDE for spark development? When I say development I would like to make changes in SPARK core and be able to contribute back. I know this question is been asked many times but I don't see a convincing answer anywhere. I use intelliJ but getting the

Usage of SparkContext within a Web container

Is use of SparkContext from a Web container a right way to process spark jobs or should we use spark-submit in a processbuilder? Are there any pros or cons of using SparkContext from a Web container..? How does zeppelin trigger spark jobs from the Web context?

[discuss] dropping Hadoop 2.2 and 2.3 support in Spark 2.0?

We've dropped Hadoop 1.x support in Spark 2.0. There is also a proposal to drop Hadoop 2.2 and 2.3, i.e. the minimal Hadoop version we support would be Hadoop 2.4. The main advantage is then we'd be able to focus our Jenkins resources (and the associated maintenance of Jenkins) to create builds

Re: running lda in spark throws exception

Spark 1.6.1

Hey All, While I'm not aware of any critical issues with 1.6.0, there are several corner cases that users are hitting with the Dataset API that are fixed in branch-1.6. As such I'm considering a 1.6.1 release. At the moment there are only two critical issues targeted for 1.6.1: - SPARK-12624 -

Re: running lda in spark throws exception

It looks like the problem is the vectors of term counts in the corpus are not always the vocabulary size. Do you mean some integers not occured in the corpus? for example, I have the dictionary is 0 - 9 (total 10 words). The docs are: 0 2 4 6 8 1 3 5 7 9 Then it will be correct If the docs are: 0
