Running Solr 6.3 on Yarn in HDP 2.4.2

theyaa — Tue, 30 May 2017 18:28:58 GMT

I have seen several posts referring to this page: https://lucidworks.com/2014/12/01/solr-yarn/ . As a solution to run Solr indexing on Yarn. those posts, and the solution, are couple years old. So, I am wondering if there has been any improvements on running Solr on Yarn in HDP?

The solution on the link above does not run Solr as a service in ambari, but rather outside the HDP cluster since it is run on the command line and not managed by Ambari.

Any solution to this please?

Well, I can't say about running Solr in YARN, but Solr can now be installed and managed by Ambari 2.5 and later. I don't think it was available in 2.4.

It should be possible to run Solr on YARN using Slider in HDP 2.4.2: https://github.com/hortonworks/slider-release/tree/HDP-2.4.2.0-tag/app-packages/solr

Theoretically you would be able to launch a Solr app on YARN through the Slider View in Ambari, but I am not sure if anyone has tried this out for Solr.

The Slider View for Ambari says it's marked as deprecated, so I am not sure of its status: https://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.18/bk_ambari-views/content/ch_using_slider_view.html
