-----------------------------------
Summary: Incorrect number of awaiting containers in slider
appmaster web UI after run flex command multiple times
Key: SLIDER-1001
URL: https://issues.apache.org/jira/browse/SLIDER-1001
Project: Slider
Issue Type: Bug
Components: appmaster, Web & REST
Affects Versions: Slider 0.80
Reporter: Weiwei Yang
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)
