Problem removing Spark 1.6 from my cluster

[#1]

Hello,

I want to remove Spark 1.6 in order to Install Spark 2.1. But when I try to remove it with this command:

sudo yum remove spark-core spark-master spark-worker spark-history-server spark-python

source: https://www.cloudera.com/documentation/enterprise/5-8-x/topics/cdh_ig_cdh_comp_uninstall.html

The packages are not found.

What should I do in order to remove Spark 1.6 from my Cluester?.

Also, in a previousstep I deleted it from my services.

I'm using CDH 5.8.0.

I forgot to mention that Spark 1.6 came with CDH 5.8. I don't know how CDH installed Spark.

@JoaquinS

To my knowledge, you don't need to remove spark 1.x in order to install spark 2.x

You can have both and CM will have separate services for spark (spark 1.x) and spark2 (spark 2.x).

Note: This is only for spark

Got the link now and it says "A Spark 1.6 service can co-exist on the same cluster as Spark 2."

@saranvisa Thanks, that worked.

Also, in order to point to the new Spark, I had to change some symbolic links and ENV variables.

export SPARK_DIST_CLASSPATH=$(hadoop classpath)
ln -sf /opt/cloudera/parcels/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/lib/spark2/bin/spark-shell /etc/alternatives/spark-shell
export SPARK_HOME=/opt/cloudera/parcels/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/lib/spark2

Where i have to set environment variables? Did i have to change in master or spark services running in slave machine's?

Please help on this!!!

If you want to use spark2-shell and spark2-submit, you don't have to set those ENV variables. I set it because I wanted to point the current spark-shell/submit to spark2.

This should be done in all the nodes that you want to use the shell and/or the submit.

I forgot to add the changes that I made for spark-sumbit.

In these files:

/opt/cloudera/parcels/CDH-5.8.0-1.cdh5.8.0.p0.42/bin/spark-submit
/opt/cloudera/parcels/CDH-5.8.0-1.cdh5.8.0.p0.42/lib/spark/bin/spark-submit

Add this ENV var:

SPARK_HOME=/opt/cloudera/parcels/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/lib/spark2
