Subject [jira] [Commented] (ACCUMULO-2076) Make it easier to connect to acccumulo
Date Wed, 14 May 2014 18:55:16 GMT


Josh Elser commented on ACCUMULO-2076:

ACCUMULO-2806 mentions securing the directories in HDFS via FileSystem permissions in which
Accumulo will write any data which is sensitive as a work-around to securing the entire Accumulo
parent directory. This is necessary because client-facing tools (shell, most notably) require
access to the {{instance_id}} in HDFS, and would likely be denied access.

The solution implemented here should allow for transparent use of tools with an existing Accumulo
instance without access to files/dirs within Accumulo's HDFS structure.

> 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.
