HiveServer2 takes long time (25+min) to startup with thousands of databases/tables/partitions

[#1]

Hello,

I have thousands of databases/tables/partitions in my metastore and noticing HS2 takes almost 20-25min to be available. I've turned on debug and notived hive-server2.log spends all the time doing the below across all of my tables and views.

2018-04-18T22:47:07,941 DEBUG [main([])]: sqlstd.SQLStdHiveAuthorizationValidator (SQLStdHiveAuthorizationValidator.java:filterListCmdObjects(148)) - Obtained following objects in  filterListCmdObjects [Object [type=TABLE_OR_VIEW, name=ued_idp_psa.stg_taxml], Object [type=TABLE_OR_VIEW, name=table1], Object [type=TABLE_OR_VIEW, name=table1], Object [type=TABLE_OR_VIEW, name=table2], Object [type=TABLE_OR_VIEW, name=table3], Object [type=TABLE_OR_VIEW, name=table4]] for user hive. Context Info: QueryContext [commandString=null, forwardedAddresses=null]

Is there a way to disable this validator or other solutions? After ~25min, i get the below message and am able to connect via beeline.

2018-04-18T 22:05:37,205 INFO  [main([])]: server.HiveServer2 (HiveServer2.java:start(508)) - Web UI has started on port 10002

Thanks,

@Nick Xu We are facing similar behaviour it is taking 30+ minutes for hiveserver2 startup. how did you disable the validator?
