I've committed this as SVN revision # 926397. As part of the change I built this version of hadoop: http://github.com/ryanobjc/hadoop-common/commits/hadoop-0.20.2-with-200-826
And it is published: http://people.apache.org/~rawson/repo/org/apache/hadoop/hadoop-core/0.20.2-with-200-826/ and http://people.apache.org/~rawson/repo/org/apache/hadoop/hadoop-test/0.20.2-with-200-826/ So to build a hadoop with the precise version that HBase trunk now depends on, you can git clone my repo above and do 'ant tar' to get yourself a hadoop 0.20.2 + HDFS-200/826. The tests should pass, but some of the sync-oriented tests were either crippled (by closing the file) or disabled (TestHLog#testSync for example).
