Rules and Guidelines for Sqoop Sources

Rules and Guidelines for Sqoop Sources

Consider the following rules and guidelines when you configure a Sqoop source in a mapping:
  • If you specify a sort condition in a mapping, the Data Integration Service ignores the Order By condition.
  • You cannot sort columns in a Sqoop source.
  • You cannot read distinct rows from a Sqoop source.
  • When you read data from an Oracle source through Sqoop and run the mapping on the Blaze or Spark engine, Sqoop treats the owner name as case sensitive.
  • Sqoop uses the values that you configure in the
    User Name
     and
    Password
     fields of the JDBC connection. If you configure the --username or --password argument in a JDBC connection or mapping, Sqoop ignores the arguments. If you create a password file to access a database, Sqoop ignores the password file.
