[jira] Created: (HBASE-2170) hbase lightweight client library as a
distribution
hbase lightweight client library as a distribution
---------------------------------------------------
Key: HBASE-2170
URL: https://issues.apache.org/jira/browse/HBASE-2170
Project: Hadoop HBase
Issue Type: Wish
Reporter: Kay Kay
As a wish - it would be nice to have a hbase client library (subset of the current hbase distribution) that needs to be present at the hbase client level to interact with the master/region servers.
>From an app integration - users of hbase can just link against the client library as opposed to getting the entire library to link against.

------------------------------------
in theory a client will only need the client/ and ipc/ directories and maybe a few more. Also zookeeper. And some other libraries.

| that would make it simple to pull those packages out into a 'hbase-client' Maven module (see HBASE-2099). We could start by getting that depending on hbase-core, and exclude all transitive dependencies but add add back in the specific ones needed (zookeeper et al).
+1 . Along ryan's suggestion - it might need some minor refactoring to carve out the separate package , but it might worth the effort to focus on the releases of the server side.

-----------------------------------
One of the things I was actually starting to look at was related to this, over on HBASE-2051 there is a utility library, of which a tiny-weeny class was an HBaseConfigurationFactory class for Spring users (such as myself).
The lightweight client library in many cases only needs the basic parameters of the zookeeper location, and the path on HDFS.
{code}
Map<String, String> propertyMap = ImmutableMap.of("hbase.rootdir",
"file:///tmp/hbase-${user.name}/hbase", "hbase.cluster.distributed", "false",
"hbase.zookeeper.quorum", "localhost");
HBaseConfigurationFactory hBaseConfigurationFactory = new HBaseConfigurationFactory(
propertyMap);
HBaseConfiguration config = (HBaseConfiguration) hbaseConfigurationFactory.getObject();
{code}
I think it's less about needing a smaller library, but more about a cleaner interface to create a logical 'connection' to the HBase cluster.
