Subject [jira] [Commented] (HBASE-11825) Create Connection and ConnectionManager
Date Mon, 15 Sep 2014 23:49:33 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14134708#comment-14134708

Lars Hofhansl commented on HBASE-11825:
---------------------------------------

I'll look at this tonight. My peeve was to get rid of the need to create threadpool and potentially
HConnection each time you make a new HTable and hence leading abominations like the HTablePools
and the weird HConnection caching we're doing. As long as we get rid of those two I am happy.

In any case, my vote is not required here :)

> This is further cleanup of the HBase interface for 1.0 after implementing the new Table
and Admin interfaces.  Following Enis's guidelines in HBASE-10602, this JIRA will generate
a new ConnectionManager to replace HCM and Connection to replace HConnection.
> For more detail, this JIRA intends to implement this portion:
> {code}
> interface Connection extends Closeable{
>   Table getTable(), and rest of HConnection methods 
>   getAdmin()
>   // no deprecated methods (cache related etc)
> }
> @Deprecated
> interface HConnection extends Connection {
>   @Deprecated
>   HTableInterface getTable()
>   // users are encouraged to use Connection
> }
> class ConnectionManager {
>   createConnection(Configuration) // not sure whether we want a static factory method
to create connections or a ctor
> }
> @Deprecated
> class HCM extends ConnectionManager {
>   // users are encouraged to use ConnectionManager
> }
> {code}
