Dave Marion commented on ACCUMULO-4328:
---------------------------------------
bq. ...with the caveat that going from 1.6.x to 1.6.6 with this capability does
not change any behavior if the feature is not enabled. And that would include
needing to modify a current user script in any way.
I believe this to be the case, that you should not have to change anything.
bq. Random ports bother me. If there is an option to assign a port, or default
to a random one if you don't care, okay - if I can only use a random port, that
seems to be a problem if we try to be more container friendly as well as port
blocking considerations.
I agree that random ports may be an issue, but its an issue that predates this
JIRA. I feel that if we are going to modify tserver.port.client to take a list
or range of values instead of 1 value for the purposes that have been stated,
then that should be a separate JIRA. However, for the purposes of this issue,
if someone wants to use this feature, then they are also choosing to deal with
random ports.
bq. The big question that I have is, even if you could do this, would you want
to?
I don't have any specific evidence to share, but in talking with [~kturner] he
expressed an interest in this feature. Maybe he can give more specifics. I will
say that one way to scale Accumulo is to add more tablet servers, and just
because you have saturated one tablet server does not mean that you have
saturated the disk or network bandwidth of the host on which it's running.
