Subject [jira] [Commented] (CARBONDATA-641) DICTIONARY_EXCLUDE is not working with 'DATE' column
Date Mon, 16 Jan 2017 10:27:26 GMT

    [ https://issues.apache.org/jira/browse/CARBONDATA-641?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15823733#comment-15823733
] 

Mohammad Shahid Khan commented on CARBONDATA-641:
-------------------------------------------------

date and timestamp type are direct dictionary column, so automatically no dictionary file
will be generated for the same.
Therefor DATE and TIMESTAMP both should not be supported in DICTIONARY_EXCLUDE option.

Input validation for the timestamp type is missing i.e. its not throwing error for the same.
Solution:
Validation should be added for the timestamp type as well.
After fix both the adding both type date and timestamp in DICTIONARY_EXCLUDE will throw error.

> I am trying to create a table with *"DICTIONARY_EXCLUDE"* and this property is not working
for *"DATE"* Data Type.
> *Query :*  CREATE TABLE uniqdata_date_dictionary (CUST_ID int,CUST_NAME string,ACTIVE_EMUI_VERSION

DECIMAL_COLUMN2 decimal(36,10),Double_COLUMN1 double, Double_COLUMN2 double,INTEGER_COLUMN1
int) STORED BY 'org.apache.carbondata.format' TBLPROPERTIES ("TABLE_BLOCKSIZE"= "256 MB","DICTIONARY_EXCLUDE"="DOB,DOJ");
> *Expected Result :* Table created.
> *Actual Result :* Error: org.apache.carbondata.spark.exception.MalformedCarbonCommandException:
DICTIONARY_EXCLUDE is unsupported for date data type column: dob (state=,code=0)
