Apache Druid

I tried with different combination of
```"maxSegmentsToMove": 1000,
"decommissioningMaxPercentOfMaxSegmentsToMove": 70,```
these 2 as well

if all 15 are decommissioning then we would have nowhere to move the segments to

the idea with decommissioning is you would decommission some subset of servers, and then Druid will move segments to the other servers

if all 15 are decommissioning it cannot do any moves, so it leaves them all alone

<@U0344FW86DD> Thanks for the response.
In fact, we have added 15 new servers so now we have 30 servers and 15 are decommissioning.

I found something interesting observation after extensive debugging related to decommissioning
```when setting druid.coordinator.balancer.strategy to cost and diskNormalized, decommissioning works fine.
however, when setting this to random decommissioning doesn't trigger movement of segments. ```
Should i go ahead and file an issue?

yeah, if that's the case, it sounds like a potential issue with `random`

here is the issue i filed.
