Description

In Hadoop 1.x (HADOOP-8230) we are going to enable durable sync by default, and remove the dfs.support.append option. What this means for you:

• HBase will work out of the box on Hadoop 1.x, no need to tell people to re-configure
• You no longer have to enable append (which can result in data loss) to enable HBase support
