Viraj Jasani updated AMBARI-25220:
----------------------------------
Description:
Ambari stores rack info for hosts in DB based on ClusterTopology data received
in Blueprint request. However, it is not necessary that blueprint would contain
correct data.
Hence, we should provide an option in UI to compare the actual Hadoop cluster
topology details with rack info that we have stored with Ambari.
was:
Ambari stores rack info for hosts in DB based on ClusterTopology data received
in Blueprint request. However, it is not necessary that blueprint would contain
correct data.
If Hadoop cluster topology changes due to commissioned/decommissioned nodes,
Ambari does not have automatic way of incorporating new changes in rack data.
Hence, we should provide an option in UI to compare the actual Hadoop cluster
topology details with rack info that we have stored with Ambari.
