Description

I have a 3 nodes yarn cluster, run hbase on it via slider. I set a pretty large heap size for each of hbase daemons so each node can only run single one container for hbase. At first, it looks like

Node1: HBASE_MASTER
Node2: HBASE_REGIONSERVER
Node3: APP_MASTER

Awaiting 0 containers

Then I run

slider flex hbase --component HBASE_REGIONSERVER 2

it causes an outstanding request, then UI shows

Awaiting 1 containers (expected)

Then I run

slider flex hbase --component HBASE_REGIONSERVER 1

The outstanding request is gone, but UI still shows

Awaiting 1 containers (unexpected)
