Subject [jira] [Commented] (ACCUMULO-2076) Make it easier to connect to acccumulo
Date Thu, 26 Dec 2013 18:47:50 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2076?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13856996#comment-13856996

Mike Drob commented on ACCUMULO-2076:
-------------------------------------

[~kturner] - The {{ZooKeeperInstance(Configuration)}} constructor is still too much work,
I think. The user still has to feed an instance name/id into the connection. I'm looking for
an entry point where the user is willing to assume that there is a single Accumulo installation
and s/he just wants to use that one. Or if there are multiple, then once of them is located
in a more 'conventional' location and takes precedence. Advanced users should absolutely be
able to specify that they want instance X, but that's just not something that's ever come
up for me.

I think Josh is heading down the right path that we need an {{accumulo-client.xml}} in addition
to {{accumulo-site.xml}} but that's a larger change than I think I want to introduce in a
point release.

> Given a program that has {{accumulo-site.xml}} on its classpath, we should be able to
abstract away from the user the steps for connecting to accumulo. I'm thinking that we need
to expose something like HdfsZooInstance through the client API, but not exactly that, since
HZI looks like it carries some extra functionality.
> # Determine the backing file system
> # Get Instance ID from the FS. 
> # Get ZooServers from accumulo-site.xml
> # Get Instance Name from ZK.
> # Create an Instance and hand it to the user.
> If this already exists in master, then maybe we need to do a better job of documenting.
Or a better job of educating me.
