This can cause Ambari Server to be the bottleneck when processing 1000+ requests. Allow the execute-stage inside a ClusterGroup to use batching. > * If some hosts have symlinks or dirs that don't belong in /usr/hdp/ then it will prevent the hosts from running "hdp-select versions". We can find these problematic hosts with an alert. > * There is currently no upgrade path from HDP 2.2 directly to 2.5. Doing a 2-step upgrade is very time consuming (only for branch 2.4 since HDP 2.2 no longer supported in Ambari 2.5). -- This message was sent by Atlassian JIRA (v6.3.15#6346)
