Subject [jira] [Updated] (HADOOP-7106) Re-organize hadoop subversion layout
Date Sun, 12 Jun 2011 05:09:51 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-7106?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated HADOOP-7106:
--------------------------------

    Attachment: gitk-example.png
                HADOOP-7106.sh
                HADOOP-7106-git.sh

Here are the final (I think) versions of the scripts to use. A few changes since previous
one:
- uses shopt -s dotglob since the previous version accidentally left common's .gitignore and
.eclipse-templates in the root dir
- does combined trees for MR-279, HDFS-1073, yahoo-merge
- had to redo the order so those trees come before "trunk" - otherwise for some reason git-svn's
tracking got messed up and HDFS-1073 ended up with a common subtree missing all of its subdirectories
except for src

Changes to the git script:
- supports merging trees from upstream branches named different things (for MR-279 and HDFS-1073)
- does a sanity check using git-ls-tree to make sure that the tree checksum in the combined
repo matches exactly the tree checksum of the last pre-7106 commit in the old repo (this is
how I found the problem with the dotfiles and the missing dirs)

I've also attached a gitk screenshot showing what it looks like in the git mirror
