[CARBONDATA-1973] User Should not Be able to give the duplicate column name
in partitioâ¦
**Jira Link:https://issues.apache.org/jira/browse/CARBONDATA-1973**
**User Should not Be able to give the duplicate column name in partition
even if its case sensitive,hive also does the same**
1.carbon.sql("CREATE TABLE uniqdata_char2(name char,id int) partitioned by
(NAME char)stored by 'carbondata' ")
name [uniqdata_char2]
18/01/03 12:44:44 WARN HiveExternalCatalog: Couldn't find corresponding
Hive SerDe for data source provider org.apache.spark.sql.CarbonSource.
Persisting data source table `default`.`uniqdata_char2` into Hive metastore in
Spark SQL specific format, which is NOT compatible with Hive.
18/01/03 12:44:44 AUDIT CarbonCreateTableCommand:
[anubhav-Vostro-3559][anubhav][Thread-1]Table created with Database name
[default] and Table name [uniqdata_char2]
res30: org.apache.spark.sql.DataFrame = []
as we can see table get created successfully
2.try same thing on hive
carbon.sql("CREATE TABLE uniqdata_char2_hive(name char,id int) partitioned
by (NAME char) ")
it gives exception
org.apache.spark.sql.AnalysisException: Found duplicate column(s) in table
definition of `uniqdata_char2_hive`: name;
at
org.apache.spark.sql.execution.datasources.AnalyzeCreateTable.org$apache$spark$sql$execution$datasources$AnalyzeCreateTable$$failAnalysis(rules.scala:198)
behaviour of carbondata should be similiar to hive
