Jean-Daniel Cryans commented on HBASE-4008:
-------------------------------------------

It's a weird use case... but looking at the .out file, I can see the following:

{code}
11/06/20 14:35:32 INFO client.HConnectionManager$HConnectionImplementation: getMaster attempt
0 of 1 failed; no more retrying.

It seems we should retry if it says that the master isn't running yet instead of ERROR'ing
out and leaving the bash script hanging.

> stop-hbase.sh stops the server successfully if and only if the server is instantiated
properly. 
> When u Run 
> start-hbase.sh; sleep 10; stop-hbase.sh; ( This works totally fine and has no issues
)
> Whereas when u run 
> start-hbase.sh; stop-hbase.sh; ( This never stops the server and neither the server gets
initialized and starts properly )
