sqoop install - sqoop download

  • Sqoop ships as one binary package however it’s compound from two separate parts client and server.
  • You need to install server on single node in your cluster.
  • This node will then serve as an entry point for all connecting Sqoop clients.
  • Server acts as a mapreduce client and therefore Hadoop must be installed and configured on machine hosting Sqoop server.
  • Clients can be installed on any arbitrary number of machines.
  • Client is not acting as a mapreduce client and thus you do not need to install Hadoop on nodes that will act only as a Sqoop client.
  • Copy Sqoop artifact on machine where you want to run Sqoop server.
  • This machine must have installed and configured Hadoop.
  • You don’t need to run any Hadoop related services there, however the machine must be able to act as an Hadoop client.
    • # Extract Sqoop  tar
tar -xf sqoop- <version>-bin-hadoop <hadoop-version>.tar.gz

# Move decompressed content to any location 
  (you can also setup soft links to sqoop directory)
mv sqoop- <version>-bin-hadoop <hadoop version>.tar.gz /opt/apache/sqoop

# Change working directory
cd /opt/apache/sqoop
