    • Hadoop Flags:

      Revert tmp files handling on DataNodes back to 0.17. sync() introduced in 0.18 has less gaurantees.

      Description

      This is a temporary work around issues discussed in HADOOP-4663.

      The proposal is to remove all the files under tmp directory, thus bringing the behavior back to 0.17. The main cost is that sync() will not be supported. This is incompatible with 0.18.x, but not with 0.17 because of this reason.
