Installing Slider - which nodes should have a client?

zack_riesland — Fri, 16 Sep 2022 15:45:06 GMT

I'm trying to install Slider on HDP 2.6.1 so I can enable LLAP.

During the install process, it wants to know which of my servers should have the client software.

Do I need the client software on all the data nodes in order to leverage the whole cluster?

Or is the client software just for performing CLI commands, etc?

The client software does not need to be installed on all the nodes, only on the node(s) where client / CLI commands will be issued. In Slider's case, Slider jars will be uploaded in a tarball to HDFS from the client and YARN will localize the tarball for Slider's containers.

@Zack Riesland Druid is not managed by slider we are working on making it managed by yarn soon [issue link].

Right. I didn't mean to imply a relationship between Druid and Slider.

Just meant: "Also want to understand how to assign processes to servers during installation of Druid."

Thanks!
