Jerry Chen commented on HADOOP-9260:
------------------------------------
I tried to find the problem that why this random phenomenon happens even at the
runtime.
The problem lies on the class path using to load the
common-version-info.properties. I checked that the
common-version-info.properties file in the hadoop-common-3.0.0-SNAPSHOT.jar has
the right information. But it loaded from another
common-version-info.properties file which is in the
hadoop-common-3.0.0-SNAPSHOT-sources.jar( when sources was packaged). While the
values of common-version-info.properties file in the
hadoop-common-3.0.0-SNAPSHOT-sources.jar are uninitialized and thus shows
values such as ${pom.version}.
In some environments, the hadoop-common-3.0.0-SNAPSHOT-sources.jar may appear
after hadoop-common-3.0.0-SNAPSHOT.jar in the class path. But in some others,
it map appear before and cause problems.
I checked that in trunk version without this problem, the
common-version-info.properties doesn't exists in
hadoop-common-3.0.0-SNAPSHOT-sources.jar. So it has no problem.

> Key: HADOOP-9260
> URL: https://issues.apache.org/jira/browse/HADOOP-9260
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: trunk-win
> Reporter: Jerry Chen
> Priority: Critical
>
> 1. Check out the trunk from
> http://svn.apache.org/repos/asf/hadoop/common/trunk/
> 2. Compile package
> m2 package -Pdist -Psrc -Pnative -Dtar -DskipTests
> 3. Hadoop version of compiled dist shows the following:
> Hadoop ${pom.version}
> Subversion ${version-info.scm.uri} -r ${version-info.scm.commit}
> Compiled by ${user.name} on ${version-info.build.time}
> From source with checksum ${version-info.source.md5}
> And in a real cluster, the log in name node shows:
> 2013-01-29 15:23:42,738 INFO org.apache.hadoop.hdfs.server.namenode.NameNode:
> STARTUP_MSG:
> /************************************************************
> STARTUP_MSG: Starting NameNode
> STARTUP_MSG: host = bdpe01.sh.intel.com/10.239.47.101
> STARTUP_MSG: args = []
> STARTUP_MSG: version = ${pom.version}
> STARTUP_MSG: classpath = ...
> STARTUP_MSG: build = ${version-info.scm.uri} -r ${version-info.scm.commit};
> compiled by '${user.name}' on ${version-info.build.time}
> STARTUP_MSG: java = 1.6.0_33
> While some data nodes with the same binary shows the correct version
> information.
