> Currently with HDFS-14017, ORFPP behaves the similar way on handling delegation as ConfiguredFailoverProxyProvider.
Specifically, given the delegation token associated with name service ID, it clones the DTs
for all the corresponding physical addresses. But ORFPPwIP requires more work than CFPP in
the sense that it also leverages VIP address for failover, meaning in addition to cloning
DT for physical addresses, ORFPPwIP also needs to clone DT for the VIP address, which is
missed from HDFS-14017. This is specific to ORFPPwIP, should not affect ORFPP.
