6Ĭheck the available sqoop utility commands: # sqoop help RDBMS JDBC Drivers for SqoopĪs a part of the future requirement we will download & move the JDBC jar files for MySQL & Oracle databases to the Sqoop library. INFO sqoop.Sqoop: Running Sqoop version: 1.4. Now let us validate sqoop is installed properly: # cd # sqoop-version So let us create an additional work directory for sqoop that will host a number of java, class, jar, avsc (Avro Schema) files corresponding to the tables when sqoop import is invoked. These abilities allow, to quickly develop MapReduce applications to process the HDFS-stored records. It can also parse the delimited-text form of a record. This class can serialize and deserialize data to and from the SequenceFile format.

The Java source code for this class is also provided, for use in subsequent MapReduce processing of the data. This class is used during the import process by Sqoop itself. A by-product of the sqoop import utility is a generated Java class which can encapsulate one row of the imported table. Now set the paths for the environment variables accordingly, in sqoop-env.sh file # vi sqoop-env.shĮxport HADOOP_COMMON_HOME=/usr/local/hadoopĮxport HADOOP_MAPRED_HOME=/usr/local/hadoop # cd # cp sqoop-env-template.sh sqoop-env.sh Next we need to configure the Sqoop environment script, which is invoked when scoop utilities are executed. # vi ~/.bashrcĮxport HADOOP_OPTS=file:/dev/./dev/urandom Next we will set the SQOOP Environment variables in the. Login to EdgeNode & follow the Installation steps as below: # cd # wget # tar -xzvf sqoop-1.4.6.bin_hadoop-2.0. > # mv sqoop-1.4.6.bin_hadoop-2.0.4-alpha # rm sqoop-1.4.6.bin_hadoop-2.0.
Get the Latest stable version of Sqoop from: So before installation check $HADOOP_HOME, $HADOOP_COMMON_HOME, $HADOOP_MAPRED_HOME, $HADOOP_CONF_DIR environment variables are already set to the path of Hadoop installation. The sqoop command-line program is a wrapper which runs the bin/hadoop script shipped with Hadoop. You invoke Sqoop through the program launch capability provided by Hadoop. We will install Sqoop in the same directory path where we already have our Hadoop binaries & configuration files /usr/local.
Sqoop Installation in EdgeNodeīefore installing Sqoop, a release of Hadoop must be installed and configured. Sqoop uses MapReduce to import and export the data, which provides parallel operation as well as fault tolerance. Sqoop automates most of this process, relying on the database to describe the schema for the data to be imported.
