[jira] Updated: (HIVE-1428) ALTER TABLE ADD PARTITION fails with a remote Thirft metastore

["Pradeep Kamath (JIRA)" <ji...@apache.org>]

Pradeep Kamath updated HIVE-1428:
---------------------------------

    Attachment: HIVE-1428-2.patch

New patch with unit tests included. Thanks for the suggestion of using threads Paul, have used that in the unit test. I have made a change in HiveConf to enable the unit test. The remaining changes in the patch are as in the first version - to throw NoSuchObjectException in getPartition() when no partition exists. This mainly changes the generated thrift code (to add throws in the method signature) and in other code which interacts with it to catch the exception and set the partition object to null.

> 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:
> [pradeepk@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 core-default.xml, mapred-default.xml and hdfs-default.xml respectively
> Hive history file=/tmp/pradeepk/hive_job_log_pradeepk_201006161709_1934304805.txt
> FAILED: Error in metadata: org.apache.thrift.TApplicationException: get_partition failed: unknown result
> FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
> [pradeepk@chargesize:~/dev/howl]
> 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.
