With several successful deployments of Hadoop (using the Hortonworks Data Platform) on record, we can help you with yours.

We can advise you on the best path forward for your case, deploy full clusters (using DevOps tools like Foreman, Puppet, and Ambari Blueprints), upgrade them to the current version of HDP and generally make the cluster perform well.

Expertise in Kerberos security, High Availability, HTTPS enablement, Ambari REST API usage, Zookeeper, YARN tuning (cgroups, ...), and general HDFS tuning.

Should you need LDAP integration with Active Directory, OpenLDAP, or FreeIPA, we have you covered.

We also have deployed Apache Zeppelin for performing data science several times, with user impersonation, and LDAP user authentication. Zeppelin runs full Spark2 and PySpark, backed by Anaconda2.5 or 3.5.

We also have quite serious expertise when it comes to CentOS 6.x and CentOS 7.x and the associated RHELs.
We can set you up on EUS versions to version lock your OS so that you do not get the ground shifting from under you feet when updating the OS.
