Subject YCSB Benchmarking for HBase
Date Wed, 03 Aug 2011 10:10:58 GMT

Anyone working on YCSB (Yahoo Cloud Service Benchmarking) for HBase ??

I am trying to run it, its giving me error:

$ java -cp build/ycsb.jar com.yahoo.ycsb.CommandLine -db

YCSB Command Line client
Type "help" for command line help
Start with "-help" for usage info
Exception in thread "main" java.lang.NoClassDefFoundError:

        at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
        ... 6 more

By the error, it seems like its not able to get Hadoop-core.jar file, but
its already in the class path.
Has anyone worked on YCSB with hbase ?
