Subject [jira] [Created] (CARBONDATA-902) NoClassDefFoundError for Decimal datatype during select queries
Date Tue, 11 Apr 2017 12:45:41 GMT
Neha Bhardwaj created CARBONDATA-902:
----------------------------------------

             Summary: NoClassDefFoundError for Decimal datatype during select queries
                 Key: CARBONDATA-902
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-902
             Project: CarbonData
          Issue Type: Bug
          Components: data-query
         Environment: Spark 2.1, Hive 1.2.1
            Reporter: Neha Bhardwaj
            Priority: Minor
         Attachments: testHive1.csv

Decimal data type raises exception while selecting the data from the table in hive.

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 testHive1(id int,name string,dob timestamp,experience
decimal,salary double,incentive bigint) stored by'carbondata' """).show 

 b) Load Data - 
scala> carbon.sql(""" load data inpath 'hdfs://localhost:54310/Files/testHive1.csv' into
table testHive1 """ ).show


2) In Hive : 

 a) Add Jars - 
add jar /home/neha/incubator-carbondata/integration/hive/carbondata-hive-1.1.0-incubating-SNAPSHOT.jar;
add jar /home/neha/incubator-carbondata/assembly/target/scala-2.11/carbondata_2.11-1.1.0-incubating-SNAPSHOT-shade-hadoop2.7.2.jar;
 
 b) Set Properties - 
set hive.mapred.supports.subdirectories=true;
set mapreduce.input.fileinputformat.input.dir.recursive=true;

c) Alter location - 
hive> alter table testHive1 set LOCATION 'hdfs://localhost:54310/opt/data/default/testhive1'
;

d) Alter FileFormat -
alter table testHive1 set FILEFORMAT
INPUTFORMAT "org.apache.carbondata.hive.MapredCarbonInputFormat"
OUTPUTFORMAT "org.apache.carbondata.hive.MapredCarbonOutputFormat"
SERDE "org.apache.carbondata.hive.CarbonHiveSerDe";

 e) Create Table -
create table testHive1(id int,name string,dob timestamp,experience decimal,salary double,incentive
bigint);

 f) Execute Queries - 
select * from testHive1;

3) Query :
hive> select * from testHive1;

Expected Output : 
ResultSet should display all the data present in the table.

Result:
Exception in thread "[main][partitionID:testhive1;queryID:8945394553892]" java.lang.NoClassDefFoundError:
