-------------------------------------

Let's take a step back. Why is this change needed in 0.98?
{quote}
Because 0.98 is the latest stable branch. If this enhancement proves itself
useful then we will be running this in production within the next few months.
{quote}
Also, on any minor upgrade e.g. 0.98.4 to 0.98.5, it should be possible to do a
rolling restart from .4 to .5. This change would seems to require two rolling
restarts, and on the second restart the ordering of the master restart will be
important.
{quote}
Since this is an opt-in feature then requiring 2 rolling restarts should be
okay?
{quote}
Without a backport of HBASE-10569, which I don't think we can backport to a
stable branch, meta updates after this patch is applied in the current state
would happen via a remote RPC call in a synchronized block as per my
understanding, which won't be ok.
{quote}
Off-hand I don't see why colocation would be required. We'll take a look if we
can come up with a less invasive solution to avoid the heavy synchronization.
