Hi,all: Recently I study hive authorization, and got some confusions: 1. Does hive 1.2.1 and later version still has grant/revoke BUG?——I found someone said that user needs to imply administrator privilege according to implements AbstractSemanticAnalyzerHook,if he want to let the administrator own the grant/revoke privilege only. But I also found a parameter "hive.users.in.admin.role",does this param makes up this deficiency？
2.Must I start up hive metastore service when SQL Standards Based Hive Authorization in conjunction with storage based authorization？（ https://cwiki.apache.org/confluence/display/Hive/SQL+Standard+Based+Hive+Authorization），and if the two combined, “hive.server2.enable.doAs" set to false? 3.Can someone please give me a tip on this class: BitSetCheckAuthorizationProvider? if I can set "hive.security.authorization.manager=org.apache.hadoop.hive.ql.security.authorization.BitSetCheckAuthorizationProvider"?What are the difference between BitSetCheckAuthorizationProvider and SQLStdHiveAuthorizerFactory? Any reply will be much appreciated. ___ Maria.
