      Append is not supported in Hadoop 1.x. Please upgrade to 2.x if you need append. If you enabled dfs.support.append for HBase, you're OK, as durable sync (why HBase required dfs.support.append) is now enabled by default. If you really need the previous functionality, to turn on the append functionality set the flag "dfs.support.broken.append" to true.

      Description

      Per HDFS-3120 for 1.x let's:

      • Always enable the sync path, which is currently only enabled if dfs.support.append is set
      • Remove the dfs.support.append configuration option. We'll keep the code paths though in case we ever fix append on branch-1, in which case we can add the config option back
