Subject [jira] [Created] (HDFS-1795) Port 0.20-append changes onto 0.20-security-203
Date Tue, 29 Mar 2011 21:33:05 GMT
Port 0.20-append changes onto 0.20-security-203
-----------------------------------------------

                 Key: HDFS-1795
                 URL: https://issues.apache.org/jira/browse/HDFS-1795
             Project: Hadoop HDFS
          Issue Type: Task
            Reporter: Andrew Purtell
         Attachments: security-append-patches.zip

Port 0.20-append changes onto 0.20-security-203.

I started with a Git repository cloned from git://git.apache.org/hadoop-common.git . Branch
'branch-0.20-security-203' was used as the starting point for the work. I then enumerated
over the 0.20-append specific patches in 'branch-0.20-append'. Each was applied if not already
via cherry pick except for as noted below. This process in effect replayed the evolution of
0.20-append branch on top of 0.20-security-203.

The specific functional changes that HBase absolutely relies upon are specially mentioned.

Generally I ran the full test suite after each change. There were a couple of exceptions where
pairs of adjacent change sets were strongly related, in which case I applied them in sequence,
then ran the test suite. During this process I encountered no test failures except for one
test in TestFileAppend4, a test brought in from the append branch, and I still need to dig
in to see if this is a real problem or if the test needs to be changed to work on top of security-203.
