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 :

Install Boto3 AWS EMR Failed attempting to download bootstrap action

Asked 2020-Jul-19 at 23:14

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

my bootstrapfile: sudo pip install boto3

Command to create cluster :

What is the mistake here ? how my bootstrap file should looks like ? Thank you

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.
