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
