How should I load jar file to read inner xml resource file?
Hi,
I'm trying to make HBase Connector for ManiforldCF.
I had put hbase.jar to connector-lib directory, so I can use HBase's classes in ManifoldCF.
But, It seems that org.apache.hadoop.hbase.HBaseConfiguration.create() can't read hbase-default.xml in hbase.jar.
It can't get hbase.defaults.for.version in hbase-default.xml, So org.apache.hadoop.hbase.HBaseConfiguration.checkDefaultsVersion(Configuration conf) throws java.lang.RuntimeException: hbase-default.xml file seems to be for and old version of HBase (null), this version is 0.94.3.
I had made CLI application and Jetty Servlet using org.apache.hadoop.hbase.HBaseConfiguration.create() in the same way. It works.
How should I load hbase.jar to read inner hbase-default.xml?
Please see following sample code and exception, and give me some advice.
SOURCE CODE:
public class HBaseRepositoryConnector extends BaseRepositoryConnector {
:
protected Configuration config = null;
:
public void connect(ConfigParams configParams) {
super.connect(configParams);
config = HBaseConfiguration.create();
:
}
:
}

Re: How should I load jar file to read inner xml resource file?
Posted by Karl Wright <da...@gmail.com>.
Also, I should point out that if you cannot (or do not want to) correct the
problem in HBase, you can instead run HBase in a separate process, and
communicate to it using RMI. Both the FileNet and Documentum connectors
use this strategy. It's usually reserved for situations where jar
dependencies are incompatible with the rest of ManifoldCF, or when there
are native code dependencies, but this would also be a valid technique if
you find you cannot get HBase to work properly in anything other than a
very specific environment.

Re: How should I load jar file to read inner xml resource file?

Hi Karl,
Took me a little while, but figured it out through a combination of
looking at the HBase code and extensive Googling.

Graeme

Re: How should I load jar file to read inner xml resource file?
Posted by Karl Wright <da...@gmail.com>.
If it works, it's better than nothing. Thanks! (Did you figure this
workaround out by looking at the hbase code? Or just wing it?)

Re: How should I load jar file to read inner xml resource file?
Posted by Graeme Seaton <li...@graemes.com>.
Hi,
I've managed to connect to HBase via the REST API by temporarily
manipulating the classloader within my connector code as below:
// Class loader voodoo to work around hbase-default.xml loading issue
ClassLoader ocl = Thread.currentThread().getContextClassLoader();
try {
//Configuration conf = HBaseConfiguration.create();
Thread.currentThread().setContextClassLoader(org.apache.hadoop.hbase.rest.client.Cluster.class.getClassLoader());
hbaseCluster = new Cluster();
hbaseCluster.add(hbaseServer,hbasePort);
hbaseClient = new Client(hbaseCluster);
hbaseTable = new RemoteHTable(hbaseClient,hbaseTablename);
} finally {
Thread.currentThread().setContextClassLoader(ocl);
}
Regards,
Graeme

Re: How should I load jar file to read inner xml resource file?
Posted by Karl Wright <da...@gmail.com>.
Hi Minoru,
The connector-lib jars are loaded using a different classloader than the
core jars in MCF. If hbase is coded properly, it should have no trouble
finding resources in those jars. But if the code in hbase tries to do
something tricky, I can imagine that it might not work. Or, hbase may just
not be coded correctly in this regard. Either way, if you understand how
the resource is being loaded we can either file a ticket/patch with hbase,
or change manifoldcf code, whichever is appropriate.
I suggest that you try to find the part of the hbase code that reads the
configuration file as a resource. Compare this against code that works.
The SharePoint connector, for instance, has a wsdd resource that it loads
which is included in the connector jar file which loads just fine.
Thanks!
Karl
