Does Hadoop 3 support Mahout?

Asked 2021-Feb-24 at 06:54

I was wondering if any Mahout version has been confirmed to work properly with any version of Hadoop 3.x. It looks like both Cloudera's and Amazon's Hadoop distribution removed Mahout when they went from Hadoop 2 to Hadoop 3. But I cannot find any reason for omitting Mahout.

Does anyone have a source or personal experience that indicates that Mahout can work with Hadoop 3?

The hadoop version recommended by trunk branch of Mahout on git hub is hadoop-2.4.1

but take a look at this dockerfile on maser branch: https://github.com/apache/mahout/blob/master/docker/build/Dockerfile

it uses spark v2.3.1 on hadoop 3.0 gettyimages/spark:2.3.1-hadoop-3.0

hope it could help

I managed to make it works. For those who want to know, please read this.

Firstly, change the Flume version. I use now flume 1.7.0 https://flume.apache.org/releases/1.7.0.html. But maybe a newer version would work, I don't want to break it down :)

Secondly, clone this repo https://github.com/cloudera/cdh-twitter-example. Inside, there is a flume.conf file. I configured it like that :

I am trying to create my cluster using bootstrap actions option (which install boto3 on all nodes), but getting always Master instance failed attempting to download bootstrap action 1 file from S3

You need to find out who pulls in slf4j-log4j. Do a "mvn:dependency:tree" on the command line in your pom.xml directory and find the dependency that pulls it in.
Put the exclusion on that dependency. Global exclusions don't work.
That should work.

ANSWER

Answered 2019-Sep-21 at 03:37

You have '/' in your SimpleDateFormatter, due to this apache fileutils will try to create directory for year, month, day:hour etc.

But the issue is you have ':' for date and hour, fileUtils will try to create a directory named "22:20" but in windows ':' is a illegal character, so fileutils will fail by throwing unable to create directory.

Instead of having '/' (or) ':', if your prefer having timestamp, i would suggest format like "YYYY-mm-dd_HH-MM-SS" before this doesn't have any illegal characters in it.

ANSWER

The problem probably exists because you are using the same name for both outputs. Since the behaviour of JSON with duplicate keys is undefined, the implementing language can choose how to behave in this situation. Presumably, the second time you are using the MasterPublicDnsName as the output name, you are overwriting the first name, which is consistent with the behaviour you are seeing.

You can either opt to use two different names, but this might makes using cross-stack references difficult, or use an Fn::If statement in the value of the output:

Mahout and Spark version compatibility

Asked 2019-Jun-28 at 14:46

I am currently using Mahout 0.13.0. When I try to use spark-itemsimilarity I get an error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/SparkConf

I suspect it may be an issue with Spark version, but I can't find what version of Spark do I need. I am currently using Spark 2.1.0.

So my question is, with which version of Spark is Mahout 0.13.0 compatible?

...

ANSWER

Answered 2017-May-18 at 14:19

I think there is a maven profile in the develop branch for building with Spark 2.x and Scala 2.11 but no artifacts published until 0.13.1 coming in a week or so.

It is compatible with both, just too many combinations of artifacts to catch up with.
