ClassNotFoundException: org.apache.hadoop.hbase.rest.Dispatcher when starting hbase master

I compiled hbase trunk and started it using bin/start-hbase.sh.


I saw some warmings like this. But I was not able to find the source code
for the missing class.
Where is the source and the jar file for the missing class?

Re: ClassNotFoundException: org.apache.hadoop.hbase.rest.Dispatcher when starting hbase master

Posted by Jonathan Gray <jl...@streamy.com>.

Digging in myself, but filed HBASE-1889.

I put up a quick patch already, would you mind giving it a try Zheng?

https://issues.apache.org/jira/browse/HBASE-1889

Thanks.
