--------------------------------------------------------------
I think it was [HBASE-15849 |
https://issues.apache.org/jira/browse/HBASE-15849] by adding this line:
{code}
+ formatter.output_str("Took %.4f seconds" % [@end_time - @start_time])
{code}
It is simple fix in graceful_stop.sh and rolling-restart.sh just "tail -2"
instead fo "tail -3".

> Project: HBase
> Issue Type: Bug
> Components: scripts
> Affects Versions: 2.0.0
> Reporter: Samir Ahmic
> Assignee: Samir Ahmic
> Priority: Critical
> Fix For: 2.0.0
>
>
> In some of our bash scripts we are piping command in hbase shell and then
> parsing response to define variables. Since 'hbase shell' output format is
> changed we are picking wrong values from output Here is example form
> gracful_stop.sh:
> {code}
> HBASE_BALANCER_STATE=$(echo 'balance_switch false' | "$bin"/hbase --config
> "${HBASE_CONF_DIR}" shell | tail -3 | head -1)
> {code}
> this will return "balance_switch true" instead of previous balancer state.
