I am running hadoop on a single node cluster and Trying to sqoop import mysql data into hive tables.
The issue is while executing sqoop job, the process taking more time and data is not imported as shown below:

you could create hive table before your execute the sqoop commend if you don't use --create-hive-table , chack your hive table exist?
eg:
sqoop import
--connect jdbc:oracle:thin:#//***/orcl
--username ***
--password ***
--table TEST
--hive-import
--create-hive-table
--hive-database myDB
--hive-table table1
--hive-override
When i run sqoop am not sure why it runs into local job runner mode and then says that i have provided invalid jobtracker url for LocalJobRunner. Can anyone tell whats going on?

Figured out the problem, i was running sqoop 1.4.5 and pointing it to the latest hadoop 2.0.0-cdh4.4.0 which had the yarn stuff also thats why it was complaining.
When i pointed sqoop to hadoop-0.20/2.0.0-cdh4.4.0 (MR1 i think) it worked.
I am new to sqoop and trying ti import a table in MYSQL table widgets table from the hadoopguide Database.
I am using Hadoop version 0.20.
and my Sqoop is sqoop-1.4.4.bin__hadoop-0.20
I am Running the command:
sqoop import --connect jdbc:mysql://localhost/hadoopguide --table widgets -m 1
This is error log I am getting

Can anyone have any idea about it.
If you have installed hive, hcatalog is installed with it. Now set the HCAT_HOME in your .bashrc as below
cd ~
gedit .bashrc
export HCAT_HOME=${HIVE_HOME}/hcatalog/
export PATH=$HCAT_HOME/bin:$PATH
source .bashrc //to refresh the .bashrc file
otherwise install hcatalog saperately and set home path.
The Hadoop release 0.20 is very old release that is lacking a lot of features. One feature that Sqoop requires is a security additions that were added in 1.x. As a result Sqoop won't work on bare 0.20, at least CDH3u1 or Hadoop 1.x is required. I would strongly suggest to upgrade your Hadoop cluster.
