Do not enable any erasure coding policies by default

    Details

    • Target Version/s:
    • Hadoop Flags:
      Incompatible change
    • Release Note:
      By default, none of the built-in erasure coding policies are enabled. Users have to explicitly enable the erasure coding policy via the hdfs configuration 'dfs.namenode.ec.policies.enabled' before setting the policy on any directories.

      Description

      As discussed on HDFS-11314, administrators need to choose the correct set of EC policies based on cluster size and desired fault-tolerance properties.

      This means we should not enable any EC policies by default, since any default value could be incorrect.
