Subject [jira] [Updated] (HIVE-14322) Postgres db issues after Datanucleus 4.x upgrade
Date Tue, 26 Jul 2016 21:53:20 GMT

     [ https://issues.apache.org/jira/browse/HIVE-14322?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sergey Shelukhin updated HIVE-14322:
------------------------------------
    Attachment: HIVE-14322.02.patch

[~thejas] the patch. I am not sure if we need to add this anywhere else... I see configs in
the source tree set autoCreateAll, but it seems like it should work without such setting (and
validateTables/etc. is not set)

> 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}
