i have set up a single node hadoop cluster and configured it to work with apache Hive, now when i imported a mysql table using the following command (using sqoop)
sqoop import --connect jdbc:mysql://localhost/dwhadoop --table orders --username root --password 123456 --hive-import
it runs successfully with some exceptions thrown after that when i do
Hive> show tales;
it does not list the orders table
if i run the import command again it gives me the error that orders dir already exists
please help me find the solution
EDIT:
i havent created any tables prior to the import, do i have to create a table order in hive before running the import. If i import another table Customers it gives me the following exception
[root#localhost root-647263876]# sqoop import --connect jdbc:mysql://localhost/dwhadoop --table Customers --username root --password 123456 --hive-import

The main thing to note is your original import fails because Sqoop tries to invoke hive but it's not in your path. Fix that problem before continuing.
Then you should just find and remove the Customers directory from hdfs (local, not in HDFS) and try again.
From what I've seen, errors of the form "Customers.java already exists" are not fatal.
You have to include --create-hive table in your query if you want Sqoop to create a table and load the data into the table in hive
When you import data into hive, Sqoop tries to create a temporary hdfs directory as staging inorder to load data to table finally. During that, its better make sure that the directory doesn't exists already.
It looks like your working directory of sqoop doesn't have enough privileges to make filesytem changes. Make sure the 'user' is the owner of the related files.

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
2 vijay sharma
3 sample singh
This is the Sqoop command I'm using (version 1.4.7)
sqoop import --connect jdbc:mysql://********:3306/sample
--table forhive --split-by id --columns id,firstname,lastname
--target-dir /home/programmeur_v/forhive
--hive-import --create-hive-table --hive-table sqp.forhive --username vaibhav -P
This is the error I'm getting

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/*

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
I'm getting the following error when I try to import-all-tables via sqoop:
sqoop import-all-tables -m 12 --connect enter code here"jdbc:mysql://quickstart.cloudera:3306/retail_db" --username=retail_dba --password=cloudera --warehouse-dir=/r/cloudera/sqoop_import

Looks like application masters are getting killed repeatedly meaning, they are not getting as much as memory as they would like. If you are just trying out sqoop on cloudera virtual machine, dont use -m 12, this will try spawn 12 parallel map tasks which you (single) machine may not be able to handle. Leave off that setting altogether or try with --direct instead . Also whats going on with --warehousedir=/r/cloudera/sqoop_import ? is /r/ as typo or it should be /user/
Try this instead :
sqoop import-all-tables \
--connect "jdbc:mysql://quickstart.cloudera:3306/retail_db" \
--warehouse-dir=/user/cloudera/sqoop_import
--username=retail_dba \
--direct
--password=cloudera;
try to load first one table instead import-all-tables, Also try to restrict your mappers while using import-all-tables , 12 mappers is hampering the memory on VM.
sqoop import-all-tables \
--connect "jdbc:mysql://quickstart.cloudera:3306/retail_db" \
--warehouse-dir=/user/cloudera/sqoop_import
--username=retail_dba \
--password=cloudera
-m 2
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.
[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?

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.
export SQOOP_HOME=/opt/cloudera/parcels/CDH-5.5.1-1.cdh5.5.1.p0.11/lib/sqoop

export HADOOP_USER_NAME=hdfs
3.

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.
