[jira] [Commented] (HADOOP-9440) Unit Test: hadoop-common2.0.3
TestIPC fails on protobuf2.5.0
[ https://issues.apache.org/jira/browse/HADOOP-9440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13658239#comment-13658239 ]
Harsh J commented on HADOOP-9440:
---------------------------------
Why do we get a protobuf exception in the first place? We shouldn't be modifying the test to capture an IOException as we don't expect that to happen. Please correct my understanding if am wrong.

> TestIPC runs normally if use protobuf2.4.1 or below version. But if using protobuf2.5.0, TestIPC.testIpcTimeout & TestIPC.testIpcConnectTimeout will fail.
