Subject [jira] [Commented] (HIVE-2742) InvalidOperationException "alter table is not possible" when using LOAD DATA INPATH OVERWRITE with database and partition
Date Tue, 19 Mar 2013 21:33:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2742?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13606859#comment-13606859
] 

Tim Goodman commented on HIVE-2742:
-----------------------------------

I had a similar issue using

    INSERT OVERWRITE TABLE [mySchema].[myTable] PARTITION([myPartition]) SELECT ...

It works the first time, and then fails the second time, presumably because in the latter
case it has to alter the existing partition.

But as a workaround, do 

    USE [mySchema]; 

before the overwrite, and then it works.

It is similar to the fact that you can't do 

    ALTER TABLE [mySchema].[myTable] ...

but instead must do

    USE [mySchema]; ALTER TABLE [myTable] ...

>          Issue Type: Bug
>          Components: Database/Schema, Metastore, Query Processor
>    Affects Versions: 0.7.1
>         Environment: reproduced on cdh3u2 (haven't tried other versions)

> Here is a repeatable procedure:
> {code}
> $ echo "test" | hadoop fs -put - test.txt
> $ echo "test2" | hadoop fs -put - test2.txt
> {code}
> Then in hive:
> {code}
> > create database catalog;
> > use catalog;
> > create table test_load (t string) partitioned by (p string);
> > use default;
> {code}
> Then the problem arises:
> {code}
> > load data inpath 'test.txt' overwrite into table catalog.test_load partition (p='test');
> Loading data to table catalog.test_load partition (p=test)
> OK
> Time taken: 0.175 seconds
> > load data inpath 'test2.txt' overwrite into table catalog.test_load partition (p='test');
> Loading data to table catalog.test_load partition (p=test)
> Moved to trash: hdfs://mycluster/user/hive/warehouse/catalog.db/test_load/p=test
> Failed with exception InvalidOperationException(message:alter is not possible)
> FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MoveTask
> {code}
