> Hive does not differentiate scheme and authority in file uris which cause
> wrong result when partition has the same path but different schema or
> authority. Here is a simple repro
> partition file path:
> asv://contain...@secondary1.blob.core.windows.net/2013-08-05/00/text1.txt
> with content "2013-08-05 00:00:00"
> asv://contain...@secondary1.blob.core.windows.net/2013-08-05/00/text2.txt
> with content "2013-08-05 00:00:20"
> {noformat}
> CREATE EXTERNAL TABLE IF NOT EXISTS T1 (t STRING) PARTITIONED BY (ProcessDate
> STRING, Hour STRING, ClusterName STRING) ROW FORMAT DELIMITED FIELDS
> TERMINATED by '\t' STORED AS TEXTFILE;
> ALTER TABLE T1 DROP IF EXISTS PARTITION(processDate='2013-08-05', Hour='00',
> clusterName ='CLusterA');
> ALTER TABLE T1 ADD IF NOT EXISTS PARTITION(processDate='2013-08-05',
> Hour='00', clusterName ='ClusterA') LOCATION
> 'asv://contain...@secondary1.blob.core.windows.net/2013-08-05/00';
> ALTER TABLE T1 DROP IF EXISTS PARTITION(processDate='2013-08-05', Hour='00',
> clusterName ='ClusterB');
> ALTER TABLE T1 ADD IF NOT EXISTS PARTITION(processDate='2013-08-05',
> Hour='00', clusterName ='ClusterB') LOCATION
> 'asv://contain...@secondary1.blob.core.windows.net/2013-08-05/00';
> {noformat}
> the expect output of the hive query
> {noformat}
> SELECT ClusterName, t FROM T1 WHERE ProcessDate=’2013-08-05’ AND Hour=’00’;
> {noformat}
> should be
> {noformat}
> ClusterA 2013-08-05 00:00:00
> ClusterB 2013-08-05 00:00:20
> {noformat}
> However it is
> {noformat}
> ClusterA 2013-08-05 00:00:00
> ClusterA 2013-08-05 00:00:20
> {noformat}
