Lefty Leverenz commented on HIVE-14322:
---------------------------------------
Doc note: This adds *datanucleus.rdbms.initializeColumnInfo* to HiveConf.java
in 2.0.2, 2.1.1, and 2.2.0 so it will need to be documented in the MetaStore
section of Configuration Properties for those releases.
* [Configuration Properties -- MetaStore |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-MetaStore]
What other values can be used, besides NONE?
Added labels TODOC2.0 (for 2.0.2), TODOC2.1.1, and TODOC2.2 (not needed if
2.1.1 is released before 2.2.0).

> With the upgrade to datanucleus 4.x versions in HIVE-6113, hive does not
> work properly with postgres.
> The nullable fields in the database have string "NULL::character varying"
> instead of real NULL values. This causes various issues.
> One example is -
> {code}
> hive> create table t(i int);
> OK
> Time taken: 1.9 seconds
> hive> create view v as select * from t;
> OK
> Time taken: 0.542 seconds
> hive> select * from v;
> FAILED: SemanticException Unable to fetch table v.
> java.net.URISyntaxException: Relative path in absolute URI:
> NULL::character%20varying
> {code}
