Zheng Hu commented on HBASE-23135:
----------------------------------
I've checked the code and found that the CellComparator.java in branch-2.0 has
the getInstance method while the branch-1.x has not, so I guess there're some
hbase-common jar conflicts problem in your project, say one hbase-common with
version 1.x and one with version 2.x, Please have a check.
It's not a bug, so please don't file a JIRA when have a question, please send a
email to user mail list instead :-) . I'll close this issue as Not a Problem.
