Paul Yang commented on HIVE-1428:
---------------------------------
The unit tests that we have for the metastore run locally, so I don't think
there's a way to use the existing framework for the thrift command - take a
look at TestHiveMetastore.java. To test this, you would have to create a new
JUnit test (or modify the existing one) to sets up a metastore server and
issues commands (create table, drop table, etc) to it. Does that seem doable?
> ALTER TABLE ADD PARTITION fails with a remote Thirft metastore

> Key: HIVE-1428
> URL: https://issues.apache.org/jira/browse/HIVE-1428
> Project: Hadoop Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 0.6.0, 0.7.0
> Reporter: Paul Yang
> Attachments: HIVE-1428.patch
>
>
> If the hive cli is configured to use a remote metastore, ALTER TABLE ... ADD
> PARTITION commands will fail with an error similar to the following:
> {code}
> [prade...@chargesize:~/dev/howl]hive --auxpath ult-serde.jar -e "ALTER TABLE
> mytable add partition(datestamp = '20091101', srcid = '10',action) location
> '/user/pradeepk/mytable/20091101/10';"
> 10/06/16 17:08:59 WARN conf.Configuration: DEPRECATED: hadoop-site.xml found
> in the classpath. Usage of hadoop-site.xml is deprecated. Instead use
> core-site.xml, mapred-site.xml and hdfs-site.xml to override properties of

> FAILED: Execution Error, return code 1 from

> [prade...@chargesize:~/dev/howl]
> {code}
> This is due to a check that tries to retrieve the partition to see if it
> exists. If it does not, an attempt is made to pass a null value from the
> metastore. Since thrift does not support null return values, an exception is
> thrown.
