Hi
We are using ES=.1.7.5
We are facing from time to time GC old GEN , leading to cluster balancing.
The balancing consume high resource from the cluster , so i consider the below procedure until we will find the root cause of the GC.
-
disable balancing- (cluster.routing.allocation.balance.threshold" : "100.0f")
-
schedule external daily job that will run ES API to Enable it for duration of 1 hour in a day ( let say between 8-9AM ) using "cluster.routing.allocation.balance.threshold" : "1.0f" (Return to Default)
-
Disable it back after 1 hour
Any risk ?
Thanks
