I loaded the data with the timestamp field unsuccessful
I loaded the data with the timestamp field unsuccessful,and timestamp field
is null.
my sql:
carbon.sql("create TABLE IF NOT EXISTS test1 (date timestamp,id string)
STORED BY 'carbondata' TBLPROPERTIES
('DICTIONARY_INCLUDE'='date','DATEFORMAT'='date:yyyy/MM/dd')")
carbon.sql("LOAD DATA inpath 'hdfs://myha/user/carbon/testdata/test4.csv'
INTO TABLE test1 options('FILEHEADER'='date,id')")
my data test4.csv:
2017/3/23,2
2017/1/11,1
2017/9/17,3
when i select:
+----+---+
|date| id|
+----+---+
|null| 1|
|null| 2|
|null| 3|
+----+---+
i print time format is correct:
println(CarbonProperties.getInstance().getProperty(CarbonCommonConstants.CARBON_TIMESTAMP_FORMAT))
yyyy/MM/dd
What could be the reason for it?
thx.

This problem has been solved. I run the same sql to another cluster is
normal, may be the cluster of carbon.properties have problems.

Hi
If the issue has be fixed?
BTW, you don't need add date column to DICTIONARY_INCLUDE, it do index for
date/timestamp columns.
