I'm using Sqoop to import tables from an Oracle database, but it's very slow, so I'm trying to use direct mode in order to speed up the import. Although standard sqoop with 1 mapper works fine, sqoop in direct mode fails (I report the complete exception below). I found the following link (http://grokbase.com/t/cloudera/cdh-user/124csac138/table-doesnt-exist-when-use-oraoop-with-sqoop) that suggests to grant the SELECT_CATALOG_ROLE role to the user, but I was denied the request by the DBA because it's too broad (too many permissions). What are the minimum Oracle grants in order to use direct mode? Below the stacktrace:[<user>@XXXX ~]$ sqoop import --connect jdbc:oracle:thin:@<ip_address>:<port>/<database> --username <username> --password XXXX --table <table> --target-dir /XXXX --as-avrodatafile --compression-codec org.apache.hadoop.io.compress.SnappyCodec --directWarning: /opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/bin/../lib/sqoop/../accumulo does not exist!
