The --ipc flag is not configurable through YARN at this time. There is a ticket open for adding this feature, YARN-8447. No one is currently working on this, so it could be helpful for you to add a comment to the ticket describing your use case.

You can configure a restart policy for each component. Add a field like the following: "restart_policy": "ON_FAILURE" The available restart policies are ALWAYS, ON_FAILURE, and NEVER. The default policy is ALWAYS.

Another command that might be informative is checking the last PID assigned: sysctl kernel.ns_last_pid

It's likely that the host has run out of PIDs, and that's why the RM can't create a new thread. Here are some commands that can help you identify whether this is the issue and increase the maximum number of PIDs allowed. Check the number of threads running: ps -elfT | wc -l Check the current pid_max: sysctl kernel.pid_max Increase the pid_max: sysctl -w kernel.pid_max=4194304

The accumulo shell will only work from a host where an Accumulo Client is installed. You can check in the Ambari UI to find out where clients are installed.

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.

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

With YARN applications, you specify the resources you want the containers to use when the app is launched. With HBase on YARN using Slider, you specify this in the resources.json file passed to the slider create command.
