Tsuyoshi OZAWA commented on HADOOP-9440:
----------------------------------------
I've tried to compile hadoop-commons' trunk with protobuf 2.5.0 and succeeded
to pass TestIPC though I needed to run "mvn clean" command explicitly under
hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common directory. Therefore, the
test failure seems to be caused the mixture of old jar file compiled with
protobuf 2.4.x and new jar file compiled with protobuf 2.5.0. If this
assumption is correct, this ticket should be marked as "Not a problem". Did you
"mvn clean" before recompile?
