Appy commented on HBASE-16044:
------------------------------
Discussed with [~stack] offline. I am fine with reverting the earlier changes
(HBASE-15965 and HBASE-15849) from branch-1 even though they are within our
operational compatibility guidelines. I think his concern for usability
triumphs here, lets make minor release (if 1.4 does comes out) easier for users.
These two changes are not critical and don't need to be necessarily backported.
It's better to do them only in major release (2.0). One of them is a step
towards putting a better system in place (interactive/non-interactive compat,
also discussed

>
> 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.
