Subject Re: Classpath problem when running Java scanner
Date Wed, 18 Aug 2010 14:50:13 GMT
No, I can't. But I have successfully run this code inside eclipse, and I 
don't know what is wrong. This is my classpath for this case:

/usr/lib/hbase/*:/usr/lib/hadoop/*:.

all jars are there since installation, what should I do?
