Have a node that was added to HDP3.1 cluster via ambari and finding that the yarn user was assigned a uid that I need specifically for another user that we need existing across multiple cluster nodes (all having the same uid). After checking the other nodes in the cluster as well as a Hortonworks post <http://community.hortonworks.com/answers/138113/view.html>, I see that the yarn user uids (as welll as for the various other service users) are randomly assigned on a per node basis.
Is there any safe way (eg. I don't know any / all of the files and processes owned by the yarn user on any of the nodes) to change the uid of the (I assume ambari-assigned) uid of the yarn user (preferably via ambari)? -- This electronic message is intended only for the named recipient, and may contain information that is confidential or privileged.
