A more concrete example

The following code

sqoop = Sqoop(fs='hdfs://remote-cluster:8020', hive_drop_import_delims=True, fields_terminated_by='\;',
enclosed_by='\'"\'', escaped_by='\\\\', null_string='\'\'', null_non_string='\'\'',
table='sample_table', target_dir='hdfs://remote-cluster/user/hive/warehouse/db/sample_table',
delete_target_dir=True, connect='jdbc:oracle:thin:@//your_ip:your_port/your_schema',
username='user', password='pwd', num_mappers=2,
bindir='/path/to/bindir/folder')

sqoop.perform_import()

will execute the following command

sqoop import -fs hdfs://remote-cluster:8020 --hive-drop-import-delims --fields-terminated-by \; --enclosed-by \'\"\' --escaped-by \\\\ --null-string \'\' --null-non-string \'\' --table sample_table --target-dir hdfs://remote-cluster/user/hive/warehouse/db/sample_table --delete-target-dir --connect jdbc:oracle:thin:@//your_ip:your_port/your_schema --username user --password pwd --num-mappers 2 --bindir /path/to/bindir/folder

TODOs

  • handle sqoop jobs
  • add missing parameters
  • more tests coverage
