See https://code.google.com/p/protobuf/issues/detail?id=493 for background information on the exception you got.
On the computer where you did the build, can you run the following command ? $ protoc --version It should print something like: libprotoc 2.5.0 If you see libprotoc 2.4.1, you need to upgrade to 2.5.0 The following file would be regenerated from protoc command : src/main/java/org/apache/hadoop/hbase/protobuf/generated/HBaseProtos.java Cheers On Sat, May 10, 2014 at 3:36 AM, raja kbv <[email protected]> wrote: > Hi Ted, > > I have recently installed hadoop-2.2.0 and hbase-0.95.19 compiled using > "sudo mvn clean package assembly:single -DskipTests -Dhadoop.profile=2.0" > as in HBASE-11076 update. > > However my region server statrup fails with error > "UnsupportedOperationException: This is supposed to be overridden by > subclasses.".
