Description

It seems that post HBASE-11886 merge, in secure mode, custom master coprocessor 's postCreateTableHandler runs as remoteRPCUser privilege so will not be able to perform operation (such as hdfs operations) which requires master user privileges.
Coprocessor developer can however, get around this by wrapping their code under master user privilege action by using User.runAsLoginUser, same can be documented.
