Sqoop Could not load mysql driver exception

0 votes

I Installed Sqoop in my local machine. Following are the config information.


export HADOOP_HOME=/home/hduser/hadoop
export HBASE_HOME=/home/hduser/hbase
export HIVE_HOME=/home/hduser/hive
export HCAT_HOME=/home/hduser/hive/hcatalog
export SQOOP_HOME=/home/hduser/sqoop

export PATH=$PATH:$HIVE_HOME/bin
export PATH=$PATH:$HCAT_HOME/bin


Version: Hadoop 1.0.3


Version: hive 0.11.0 

Mysql Connector driver

version: mysql-connector-java-5.1.29

"The driver is copied to the lib folder of sqoop"

Sqoop :

version: sqoop 1.4.4

After making all the installation I create a table in mysql named practice_1, But when I run the load command to load data from mysql to hdfs the command throws an exception:

ERROR sqoop.Sqoop: Got exception running Sqoop: java.lang.RuntimeException: Could not     load db driver class: com.mysql.jdbc.Driver

You need database driver in 'SQOOP' classpath check this It has wonderful explanation about the 'SQOOP'

SQOOP has other options like

Ex: --driver com.microsoft.jdbc.sqlserver.SQLServerDriver -libjars=".*jar"

from here

You can use Sqoop with any other JDBC-compliant database. First, download the appropriate JDBC driver for the type of database you want to import, and install the .jar file in the $SQOOP_HOME/lib directory on your client machine. (This will be /usr/lib/sqoop/lib if you installed from an RPM or Debian package.) Each driver .jar file also has a specific driver class which defines the entry-point to the driver. For example, MySQL's Connector/J library has a driver class of com.mysql.jdbc.Driver. Refer to your database vendor-specific documentation to determine the main driver class. This class must be provided as an argument to Sqoop with --driver
