HIVE-29669:EXPLAIN DDL fails on ACID tables with "Cannot find valid write ID list" when HIVE_AUTHORIZATION_ENABLED is enabled

[ramitg254]

What changes were proposed in this pull request?

correction to use wrong conf while execution of explain ddl query for transactional tables

Why are the changes needed?

hive/ql/src/java/org/apache/hadoop/hive/ql/security/authorization/plugin/HiveMetastoreClientFactoryImpl.java

Line 43 in 4c4a618

return Hive.get(hiveConf, false).getMSC();

this piece of code repoints the conf under Hive.java which gets used in

hive/ql/src/java/org/apache/hadoop/hive/ql/exec/DDLPlanUtils.java

Line 525 in 4c4a618

List<ColumnStatisticsObj> tableColumnStatistics = Hive.get().getTableColumnStatistics(

and lacks valid transaction keys which cause this failure as querystate conf contains these keys rather than session conf so Hive.java should be repointed to querystate conf for query execution

No
