Describes how to add various roles to a Data Fabric node.
About this task
NOTE
When Collectd is
installed on a node with YARN ResourceManager or NodeManager, running
configure.sh -R
, to add or remove roles on the node, triggers
these services to restart. During a restart, the NodeManager and ResourceManager are
temporarily unavailable for new application submission. A patch is available to
resolve this behavior. See Applying
Patches.Procedure
