Subject [jira] [Commented] (HADOOP-9207) version info source checksum does not include all source files
Date Mon, 14 Jan 2013 21:44:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9207?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13553154#comment-13553154
] 

Chris Nauroth commented on HADOOP-9207:
---------------------------------------

See HADOOP-8924 for some earlier discussion on this topic.  We could either calculate a single
MD5 checksum across the whole project and use it for both HDFS and YARN, or calculate separate
checksums per module, but with inclusion of the Common code in each one.

> The build process takes an MD5 checksum of the source files in Common and YARN.  The
HDFS version info command prints the checksum from Common.  The YARN version info command
prints the checksum from YARN.  This is incomplete in that the HDFS source code is never included
in the checksum, and 2 different YARN builds with the same YARN code but different Common
code would have the same checksum.
