NoClassDefFoundError :...regionserver/ConstantSizeRegionSplitPolicy

[Chang Chao <ch...@gmail.com>]

Hi,All

I am facing the NoClassDefFoundError of
org/apache/hadoop/hbase/regionserver/ConstantSizeRegionSplitPolicy class
problem in my junit executions under cdh5.2.1 + phoenix 4.1.0 env,

What I did is that I wrote a junit method rule,in the rule,a
datasource(phoenix on hbase) is retrieved through spring config,
the following exception happend when the connection is being created from
datasource.

Here is the stacktrace.java.lang.NoClassDefFoundError:
