Ted Yu commented on HBASE-4213:
-------------------------------
I got the following when applying patch v4:
{code}
patching file
src/test/java/org/apache/hadoop/hbase/regionserver/handler/TestOpenRegionHandler.java
Hunk #1 FAILED at 135.
1 out of 1 hunk FAILED -- saving rejects to file

When I tried to compile the code:
