----------------------------------------
Summary: selecting table data having a column of "date" type throws exception in hive
Key: CARBONDATA-950
URL:
https://issues.apache.org/jira/browse/CARBONDATA-950 Project: CarbonData
Issue Type: Bug
Components: data-query
Environment: spark 2.1, hive 1.2.1
Reporter: Neha Bhardwaj
Priority: Minor
Attachments: my_user.csv
selecting data from a hive table containing a column of date datatype is failing to render output.
Steps to reproduce:
1) In Spark Shell :
a) Create Table -
import org.apache.spark.sql.SparkSession
import org.apache.spark.sql.CarbonSession._
val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("hdfs://localhost:54310/opt/data")
scala> carbon.sql(" create table my_user(id int, name string,dob date) stored by 'carbondata' ").show
b) Load Data -
scala> carbon.sql(""" load data inpath 'hdfs://localhost:54310/Files/my_user.csv' into table my_user """ ).show
2) In Hive :
a) Add Jars -
add jar /home/neha/incubator-carbondata/assembly/target/scala-2.11/carbondata_2.11-1.1.0-incubating-SNAPSHOT-shade-hadoop2.7.2.jar;
add jar /opt/spark-2.1.0-bin-hadoop2.7/jars/spark-catalyst_2.11-2.1.0.jar;
add jar /home/neha/incubator-carbondata/integration/hive/carbondata-hive-1.1.0-incubating-SNAPSHOT.jar;
b) Create Table -
create table my_user(id int, name string,dob date);
c) Alter location -
hive> alter table my_user set LOCATION 'hdfs://localhost:54310/opt/data/default/my_user' ;
d) Set Properties -
set hive.mapred.supports.subdirectories=true;
set mapreduce.input.fileinputformat.input.dir.recursive=true;
d) Alter FileFormat -
alter table my_user set FILEFORMAT
INPUTFORMAT "org.apache.carbondata.hive.MapredCarbonInputFormat"
OUTPUTFORMAT "org.apache.carbondata.hive.MapredCarbonOutputFormat"
SERDE "org.apache.carbondata.hive.CarbonHiveSerDe";
e) Query:
select * from my_user;
Expected Output:
display all the data of table my_user.
Actual Output:
Failed with exception java.io.IOException:java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long
