Nick Allen reassigned METRON-2175:
----------------------------------
Assignee: Nick Allen
> Introduce HBase Connection Abstractions for HBase 2.0.2
> -------------------------------------------------------
>
> Key: METRON-2175
> URL: https://issues.apache.org/jira/browse/METRON-2175
> Project: Metron
> Issue Type: Sub-task
> Reporter: Nick Allen
> Assignee: Nick Allen
> Priority: Major
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> The major change with HBase in migrating Metron to 2.0.2 is that connection
> management must now be managed by the client. Previously this was managed
> internally within the HBase client.
> More specifically, previously you could just instantiate a Table whenever you
> like and not worry about closing it. Now you must first establish a
> Connection and from that Connection, you can create a Table. Both of those
> need to be closed after use. A Connection can be shared by multiple threads,
> but a Table cannot be shared.
> Most of our existing abstractions were not designed to handle connection
> management, specifically closing the Connection and Table resources after
> use. This is why the HBase upgrade is quite involved.
> This Jira will introduce the new abstractions that allow Metron to interact
> with HBase 2.0.2, but not remove the existing ones. I will then introduce
> additional issues to start using these new abstractions in the Metron code
> base. Finally, the existing abstractions that do not work with HBase 2.0.2
> will be removed as a final step.
