I have following sqoop to import data from oracle to hive instance.   sqoop import -Dhadoop.security.credential.provider.path=${keystore_custom} \ -Dmapred.job.queue.name=${queue} \ --connect jdbc:oracle:thin:@${hostname}:${port}:${custom_db} \ --username ${username} \ --password-alias ${custom_alias} \ --query 'SELECT * FROM table C where $CONDITIONS' \ --hive-import \ --delete-target-dir \ --null-string '\\N' \ --null-non-string '\\N' \ --hive-drop-import-delims \ --hive-table hive_instance.table \ --target-dir /user/hive_instance/table -m 1;   Above sqoop works normally when triggered from edge node.
