Ruixuan Zhang updated KYLIN-5460:
---------------------------------
Description: When resource group is turned on, using EnhancedUnitOfWork to
write metadata will check if current owner has the write permission, that is,
whether the node is in the build resource group. The new feature of providing
more flexible runtime join will force KYLIN to go into maintenance mode when
using script to update and write metadata, this will have mocked node IP:0000
owning the epoch and since the mocked node is not in the build resource group,
it will cause write failure. (was: When resource group is turned on, using
EnhancedUnitOfWork to write metadata will check if current owner has the write
permission, that is, if the node is in the build resource group. The new
feature of providing more flexible runtime join will force KYLIN to go into
maintenance mode when using script to update and write metadata, this will have
mocked node IP:0000 occupy the epoch and since the mocked node is not in the
build resource group, which causes write failure.)
