You can locate them through ambari. When you (re)start a service you can click on the operations > operation > tasks and inspect the commands: If you look closely the script being executed for restarting the nodemanager is at 08:53:13,592. The script is located in /usr/hdp/current/hadoop-yarn-nodemanager/sbin/yarn-daemon.sh. This file is shipped with the distribution. Before executing this file users are created and config is pushed. The preparation of these steps happen on the AmbariServer. You can search for the python scripts. For example the nodemanager in the /var/lib/ambari-server/resources/common-services/YARN/2.1.0.2.0/package/scripts/. If you change one these files, don't forget to restart the ambari-server, because the files are cached. After an ambari-server upgrade these changes will be overridden reverted. Hope this helps. ...

@Benjamin Leonhardi could you please tell me how to actually increase the hash cache? I agree 100MB is not much. I'm running an HDP 2.6.5 cluster with HBase 1.1.2 and Phoenix enabled. I couldn't find the property phoenix.query.maxServerCacheBytes defined in hbase-site.xml config file, so I tried adding it in the "Custom hbase-site" section in Ambari and setting it to 500Mb as shown in the picture below: Now I can see the variable defined in hbase-site.xml, but I am still getting the following error "...maximum allowed size (104857600 bytes)" even though I have changed that setting to 500MB). Any ideas or suggestions? Thanks in advance! ... View more
