A working equivalent of sync() in HDFS, and support for it. See http://www.cloudera.com/blog/2010/07/whats-new-in-cdh3-b2-hbase/ , especially: "HDFS improvements for HBase – along with the HDFS team at Facebook, we have contributed a number of important bug fixes and improvements for HDFS specifically to enable and improve HBase. These fixes include a working sync feature that allows full durability of every HBase edit, plus numerous performance and reliability fixes."
You could also use the 0.20-append branch of ASF hadoop-common: http://github.com/apache/hadoop-common/tree/branch-0.20-append but CDH3 offers other benefits, check out their blog.
