Bugs: AMBARI-20490
https://issues.apache.org/jira/browse/AMBARI-20490
Repository: ambari
Description
-------
On large-scale clusters over 1000 nodes, performance during Express Upgrade can
be very slow and it takes more time to fix potential errors.
We can remedy these with the following fixes:
* "hdp-select set all" is currently ran in the ClusterGroup with a single stage
instead of batching. 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).
