    • Type: Improvement
    • Status: Closed
    • Priority: Critical
    • Resolution: Fixed
    • Affects Version/s: 0.23.0, 2.0.0-alpha, 3.0.0-alpha1
    • Fix Version/s: 0.23.7, 2.1.0-beta
    • Component/s: ipc
    • Labels:
      None

      Description

      Querying UGI.getCurrentUser is synch'ed and inefficient for short-lived RPC requests. Since the connection already contains the UGI, there should be a means to query it directly and avoid a call to UGI.getCurrentUser.
