Some of the important Features of the Sqoop :

  • Sqoop also helps us to connect the result from the SQL Queries into Hadoop distributed file system.
  • Sqoop helps us to load the processed data directly into the hive or Hbase.
  • It performs the security operation of data with the help of Kerberos.
  • With the help of Sqoop, we can perform compression of processed data.
  • Sqoop is highly powerful and efficient in nature.

Sqoop job creates and saves the import and export commands. It specifies parameters to identify and recall the saved job. This re-calling or re-executing is used in the incremental import, which can import the updated rows from RDBMS table to HDFS.
