Subject Re: org.apache.hadoop.hbase.coprocessor.TestClassLoading failing in Eclipse, not in shell...
Date Wed, 30 Jan 2013 21:32:29 GMT
Hi Adrian,

Yes, I tried it with a pure JUnit test in eclipse.

I have submitted https://issues.apache.org/jira/browse/HBASE-7718 for
this issue. I tried it into Eclipse and with mvn command line and both
are working fine.
