    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Minor
    • Resolution: Fixed
    • Affects Version/s: 3.0.0
    • Fix Version/s: 3.2.0
    • Component/s: erasure-coding
    • Labels:
      None
    • Environment:

      3 Node SUSE Linux cluster

    • Hadoop Flags:
      Incompatible change, Reviewed
    • Release Note:
      After this change, attempt to unsetErasureCodingPolicy() on a directory without EC policy explicitly set on it, will get NoECPolicySetException.

      Description

      No error message thrown for unsetting EC policy of the directory inherits the erasure coding policy from an ancestor directory

      Steps :-

      --------------

      • Create a Directory
      • Set EC policy for the Directory
      • Create a file in-side that Directory
      • Create a sub-directory inside the parent directory
      • Check both the file and sub-directory inherit the EC policy from parent directory
      • Try to unset EC Policy for the file and check it will throw error as [ Cannot unset an erasure coding policy on a file]
      • Try to unset EC Policy for the sub-directory and check it will throw a success message as [Unset erasure coding policy from <path>]
        instead of throwing the error message,which is wrong behavior

      Actual output :-

      No proper error message thrown for unsetting EC policy of the directory inherits the erasure coding policy from an ancestor directory
      A success message is displayed instead of throwing an error message

      Expected output :-

      Proper error message should be thrown while trying to unset EC policy of the directory inherits the erasure coding policy from an ancestor directory
      like error message thrown while unsetting the EC policy of a file inherits the erasure coding policy from an ancestor directory
