Fixing Common Issues with Cloudera HDP Docker

Hortonwords Data Platform (HDP) is a very useful out-of-the-box system with everything you need to get started doing Big Data Machine Learning.

It comes packed with awesome tools such as:

• Hadoop – big data file store
• Hive – SQL translation library to access the data in the big data file store
• HBase – Big Data Database
• Spark – Compute Cluster Manager
• Ambari – to manage everything else

If you are having issues with your Docker installation after following: https://www.cloudera.com/tutorials/sandbox-deployment-and-install-guide/3.html here are some fixes:

Issues with Docker sandbox-proxy container not starting right after installation?

If you are having issues with the sandbox-proxy container starting, clean-up your setup by removing the containers with:

docker rm -f sandbox-hdp sandbox-proxy

Then edit docker-deploy-{HDPversion}.sh and replace “==” with “=” where you see the if statements for $flavor:

# start the docker container and proxy
if [ "$flavor" == "hdf" ]; then
 hostname="sandbox-hdf.hortonworks.com"
elif [ "$flavor" == "hdp" ]; then
 hostname="sandbox-hdp.hortonworks.com"
fi

to:

# start the docker container and proxy
if [ "$flavor" = "hdf" ]; then
 hostname="sandbox-hdf.hortonworks.com"
elif [ "$flavor" = "hdp" ]; then
 hostname="sandbox-hdp.hortonworks.com"
fi
