sqoop export to hana failed - hadoop

when I want to export data from sqoop to hana DB, I receive error message.
Here is sqoop call
sqoop export \
--connect "jdbc:sap://saphana:30115" \
--username username \
--password password \
--table "INTERFACE_BO.WR_CUSTOMER_DATA" \
--columns "WEEK_DAY_START,SALES_ORG,REG_ORDERS_CNT,REG_EMAILS_CNT,UNIQUE_EMAILS" \
--driver "com.sap.db.jdbc.Driver" \
--export-dir "/user/hive/warehouse/export.db/weekly_holding_report" \
--input-fields-terminated-by '\t'
This is the way how I create table
CREATE TABLE weekly_holding_report
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
stored as textfile
AS
SELECT
...
I also tried many variants of stored as like: stored as parquet, etc.. but without any change
And here is reposponse

Does anybody know what am I doing wrong?
Thanks for help!

Have you tried adding an sqoop argumment --m 1
this is basically for giving number of mappers so in this case try with mapper = 1
is your data is too huge(more than 1 gb's) then increase number of mappers

Check the logs for the corresponding job id, in your case job_1476740951886_1458. There must be some permission or connectivity issue(with the given saphana url), that is why it transferred zero bytes.

ERROR hive.HiveConfig: Could not load org.apache.hadoop.hive.conf.HiveConf. Make sure HIVE_CONF _DIR is set correctly

I am trying to import data from sqoop to hive
MySQL
use sample;
create table forhive( id int auto_increment,
firstname varchar(36),
lastname varchar(36),
primary key(id)
);
insert into forhive(firstname, lastname) values("sample","singh");
select * from forhive;
1 abhay agrawal

sqoop import --connect jdbc:mysql://********:3306/sample

I'm just unable to figure out what mistake I'm making here. Please guide!
Download the file "hive-common-0.10.0.jar" by googling. Place this in "sqoop/lib" folder. This solution worked for me.
Go to $HIVE_HOME/lib directory using
cd $HIVE_HOME/lib
then copy hive-common-x.x.x.jar and paste it in $SQOOP_HOME/lib using
cp hive-common-x.x.x.jar $SQOOP_HOME/lib
You need to download the file hive-common-0.10.0.jar and copy it to $SQOOP_HOME/lib folder.
edit your .bash_profile ,then add HADOOP_CLASSPATH
vim ~/.bash_profile
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HIVE_HOME/lib/*
source ~/.bash_profile
I got the same issue when I tried to import data from MySQL to Hive with the following command:
sqoop import --connect jdbc:mysql://localhost:3306/sqoop --username root --password z*****3 --table users -m 1 --hive-home /opt/hive --hive-import --hive-overwrite
Finally, these environment variables made it work perfectly.
export HIVE_HOME=/opt/hive
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HIVE_HOME/lib/*
export HIVE_CONF_DIR=$HIVE_HOME/conf

import-all-tables hanging in during hive-import

[cloudera#quickstart ~]$ sqoop import-all-tables --connect="jdbc:mysql://serverip:3306/dbname"
--username=xxx --password=yyy -m 1 --hive-import --hive-overwrite
--create-hive-table --hive-database sqoopimport --hive-home /user/hive/warehouse
It is running upto map-reduce and during hive import it is hanging in below step, am I doing any mistake?

No tables are created inside HIVE but data is crerated inside hdfs

I am new to HDFS and I am trying to import data from my oracle 12c db. I have a table EMP, it needs to be imported inside hdfs as well as hive tables.
My data is getting created inside hdfs ('/user/hdfs' a folder 'EMP' gets created). But when I open hive query editor and type 'show tables' I don't get to see any tables here. I need the tables to be created inside HIVE as well
I am running the following commands.
1. Since am running sqoop as root user
usermod -a -G supergroup hardik
2.

I have tried all variations of sqoop import commands but none have succeeded. I am even more confuse today. Please help. Please do not mark this as duplicate.
From your logs, I found two errors:
Error: EMP : Unsupported major.minor version 52.0
Unsupported major.minor version 52.0 comes when you are trying to run a class compiled using Java 1.8 compiler into a lower JRE version e.g. JRE 1.7 or JRE 1.6. Check more here.
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. AlreadyExistsException(message:Table EMP already exists)
Your job worked till taking data to hdfs. You must be trying same command again without deleting this /user/hdfs/EMP directory. That's why you got this error.

Oracle Sqoop Retrieves 0 Records

I have a table in Oracle XE 11g
SQL> create table bloblkup (
2 id NUMBER PRIMARY KEY,
3 name varchar(28) NOT NULL,
4 fdata BLOB
5 );
Table created.
SQL> desc bloblkup
Name Null? Type
----------------------------------------- -------- ----------------------------
ID NOT NULL NUMBER
NAME NOT NULL VARCHAR2(28)
FDATA BLOB
populated with
SQL> select * from bloblkup;
ID NAME
---------- ----------------------------
FDATA
--------------------------------------------------------------------------------
1 photo.jpg
032135435135
From the cluster I attempt to Sqoop this table into HDFS
sqoop import --connect jdbc:oracle:thin:#Rhea:1521:xe --username SYSTEM --password oracle --table bloblkup --columns 'name' -m 1
that executes to completion every time but provides INFO
15/03/24 09:14:39 INFO mapreduce.ImportJobBase: Retrieved 0 records.
I can retrieve databases and tables.
I am logging in as system which created and owns the table.
I have also found that I can query tables such as the all_tables and return rows just not table that I have created through sqlplus>
I added --m 1 flag after the first attempted failed due to being unable to located an primary key for the table. I added a primary key to the table using alter table with no change.
thoughts?
console output:
[root#sandbox ~]# sqoop import --connect jdbc:oracle:thin:#Rhea:1521:xe --username SYSTEM --password oracle --table bloblkup --columns 'name' -m 1

Update the Oracle driver version ojdbc6.jar appears to work, but be flaky with JDK 1.7 use ojdbc7.jar
Also, you must "commit" database changes in SQLPLUS for them to persist
Check whether jdbc driver is under $SQOOP_HOME/lib if not copy the ojdbc6.jar file to:
/usr/lib/sqoop/lib/ directory
Provide more details from console.
If every thing is fine then add --target-dir to see output on that specific directory.
/usr/bin/sqoop import --connect jdbc:oracle:thin:system/system#<IP address>:1521:xe --username <username> -P--table <database name>.<table name> --columns "<column names>" --target-dir <target directory path> -m 1
