Subject [jira] Updated: (HIVE-1428) ALTER TABLE ADD PARTITION fails with a remote Thirft metastore
Date Wed, 23 Jun 2010 01:10:50 GMT

     [ https://issues.apache.org/jira/browse/HIVE-1428?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Paul Yang updated HIVE-1428:
----------------------------

    Description: 
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}
[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]
{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.

This is due to a check that tries to retrieve the partition to check if it exists. If it does
not, an attempt is made to pass a null partition value from the metastore. Since thrift does
not support null return values, an exception is thrown when the CLI is configured to use a
remote metastore.
