Affects Version/s: None
Fix Version/s: 3.0.0-alpha2
Hadoop Flags:Incompatible change
Release Note:The maximum applications the RM stores in memory and in the state-store by default has been lowered from 10,000 to 1,000. This should ease the pressure on the state-store. However, installations relying on the default to be 10,000 are affected.
my cluster has 120 nodes.
I configured RM Restart feature.
unfortunately I did not configure yarn.resourcemanager.state-store.max-completed-applications.
so that property configured default value 10,000.
I have restarted RM due to changing another configuartion.
I expected that RM restart immediately.
recovery process was very slow. I have waited about 20min.
realize missing yarn.resourcemanager.state-store.max-completed-applications.
its default value is very huge.
need to change lower value or document notice on RM Restart page.
