Hi,
We are trying to connect to HBase server and getting a
NoClassDefFoundError. The environment specification is -
Windows 7 x64
java version "1.6.0_27"
Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)
Rhino: 2.2.0.7
CYGWIN_NT-6.1-WOW64 (version 2.378)
HBase 0.90.2
Hadoop 0.20(-append-r1056497)
And the exception is -
Exception occurred in target VM: Could not initialize class $Proxy25
java.lang.NoClassDefFoundError: Could not initialize class $Proxy25

We also noticed that it runs perfectly from Linux environment. Is this
a known issue or expected behavior?
Thank you,
