Daniel Voros resolved HIVE-20872.
---------------------------------
Resolution: Duplicate
> Creating information_schema and sys schema via schematool fails with parser
> error
> ---------------------------------------------------------------------------------
>
> Key: HIVE-20872
> URL: https://issues.apache.org/jira/browse/HIVE-20872
> Project: Hive
> Issue Type: Bug
> Components: Hive, HiveServer2, Metastore, SQL
> Affects Versions: 3.1.0, 3.1.1
> Environment: Apache Hive (version 3.1.1)
> Hive JDBC (version 3.1.1)
> metastore on derby embedded, derby server, postgres server
> Apache Hadoop (version 2.9.1)
> Reporter: Carsten Steckel
> Priority: Critical
>
> it took quite some time to figure out how to install the "information_schema"
> and "sys" schemas (thanks to
> https://issues.apache.org/jira/browse/HIVE-16941) into a hive 3.1.0/3.1.1 on
> hdfs/hadoop 2.9.1 and I am still unsure if it is the proper way of doing it.
> when I execute:
>
> {noformat}
> hive@hive-server ~> schematool -metaDbType derby -dbType hive -initSchema
> -url jdbc:hive2://localhost:10000/default -driver
> org.apache.hive.jdbc.HiveDriver"
> {noformat}
> I receive an error (from --verbose log):
>
> {noformat}
> [...]
> Error: Error while compiling statement: FAILED: SemanticException
> org.apache.hadoop.hive.ql.metadata.InvalidTableException: Table not found
> _dummy_table (state=42000,code=40000)
> org.apache.hadoop.hive.metastore.HiveMetaException: Schema initialization
> FAILED! Metastore state would be inconsistent !!
> [...]
> {noformat}
>
> It seems to be the last statement during setup of the sys-schema causes the
> issue. When executing it manually:
>
>
> {noformat}
> 0: jdbc:hive2://localhost:10000> CREATE OR REPLACE VIEW `VERSION` AS SELECT 1
> AS `VER_ID`, '3.1.0' AS `SCHEMA_VERSION`, 'Hive release version 3.1.0' AS
> `VERSION_COMMENT`;
> Error: Error while compiling statement: FAILED: SemanticException
> org.apache.hadoop.hive.ql.metadata.InvalidTableException: Table not found
> _dummy_table (state=42000,code=40000)
> {noformat}
>
> I have tried to switch the metastore_db from derby embedded to derby server
> to postgresql and made sure the changed metadatabases each worked, but
> setting up the information_schema and sys schemas always delivers the same
> error.
> Executing only the select part without the create view works:
>
> {noformat}
> 0: jdbc:hive2://localhost:10000> SELECT 1 AS `VER_ID`, '3.1.0' AS
> `SCHEMA_VERSION`, 'Hive release version 3.1.0' AS `VERSION_COMMENT`;
> +---------+-----------------+-----------------------------+
> | ver_id | schema_version | version_comment |
> +---------+-----------------+-----------------------------+
> | 1 | 3.1.0 | Hive release version 3.1.0 |
> +---------+-----------------+-----------------------------+
> 1 row selected (0.595 seconds)
> {noformat}
> It seems to be related to: HIVE-19444
