Subject [jira] [Commented] (HBASE-10602) Cleanup HTable public interface
Date Sun, 04 May 2014 01:04:06 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13988882#comment-13988882
] 

Andrew Purtell commented on HBASE-10602:
----------------------------------------

bq. It has been a discussed (in the master redesign issue, and by Stack in RB for this issue)
that at the RPC layer, we would want to fire up a request like createTable to master, and
get a token back so that we can query the results later with it.

Server task management with a client API for querying task status was proposed also on HBASE-10170
for long running coprocessor endpoint invocations.

> HBASE-6580 replaced the preferred means of HTableInterface acquisition to the HConnection#getTable
factory methods. HBASE-9117 removes the HConnection cache, placing the burden of responsible
connection cleanup on whomever acquires it.
> The remaining HTable constructors use a Connection instance and manage their own HConnection
on the callers behalf. This is convenient but also a surprising source of poor performance
for anyone accustomed to the previous connection caching behavior. I propose deprecating those
remaining constructors for 0.98/0.96 and removing them for 1.0.
> While I'm at it, I suggest we pursue some API hygiene in general and convert HTable into
an interface. I'm sure there are method overloads for accepting String/byte[]/TableName where
just TableName is sufficient. Can that be done for 1.0 as well?
