Of course this looks like HBase jar is not on the classpath, but it is -
my source file compiles with the same classpath settings.

Hello,
I tried to write custom HBase scanner in Java. It compiles successfully, but
I have problem with running it. I always get exception:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/hbase/HBaseConfiguration
at AdserverLogsScanner.<init>(AdserverLogsScanner.java:28)
at AdserverLogsScanner.main(AdserverLogsScanner.java:70)
Caused by: java.lang.ClassNotFoundException:

... 2 more
this is the line that is causing it:
28: config = HBaseConfiguration.create();
I'm using new API for that.
I have HBase working (I've used shell and web interface on this setup) and I
have added correct classpath to this class (jar):
System.setProperty("java.class.path",
"/usr/lib/hbase/*:/usr/lib/hadoop/*:.");
(with this classpath it compiles)
Please help me, because I can't possibly see that is wrong here.
Thank you in advance for any answers and comments.
