During a meeting with your customer's IT security team, you are asked the names of the main OS users and groups for the Big Data Appliance.
Which users are created automatically during the installation of the Oracle Big Data
Appliance?

• A.bda, cdh5, and oracle

How is Oracle Loader for Hadoop (OLH) better than Apache Sqoop?

• A.OLH performs a great deal of preprocessing of the data on the Oracle database before loading it into NoSQL.
• B.OLH performs a great deal of preprocessing of the data on the Oracle database before loading it into Hadoop.
• C.OLH is fully supported on the Big Data Appliance. Apache Sqoop is not supported on the Big Data Appliance.
• D.OLH does not use MapReduce to process any of the data, thereby increasing performance.
• E.OLH performs a great deal of preprocessing of the data on Hadoop before loading it into the database.

Your customer needs to analyze large numbers of log files after combining them with customer profile and interaction data. The customer wants to be able to analyze these files back to their go-live date, which was last October.

• B.hive> create table logs as select * from sample.log;
• C.hive> LOAD DATA LOCAL INPATH 'sample.log' OVERWRITE INTO TABLE logs;hive>
  CREATE TABLE logs (t1 string, t2 string, t3 string, t4 string, t5 string, t6 string, t7 string)
  ROW FORMAT DELIMITED FIELDS TERMINATED BY ' ';
• D.hive> CREATE TABLE logs (t1 string, t2 string, t3 string, t4 string, t5 string, t6 string, t7 string) ROW FORMAT DELIMITED FIELDS TERMINATED BY ' ';hive> LOAD DATA
  LOCAL INPATH 'sample.log' OVERWRITE INTO TABLE logs;
• E.hive> CREATE TABLE logs (t1 string, t2 string, t3 string, t4 string, t5 string, t6 string, t7 string) ROW FORMAT DELIMITED FIELDS TERMINATED BY ' ';
