CORRECT TEXT
Problem Scenario 28 : You need to implement near real time solutions for collecting information when submitted in file with below
Data
echo "IBM, 100, 20160104" >> /tmp/spooldir2/.bb.txt
echo "IBM, 103, 20160105" >> /tmp/spooldir2/.bb.txt
mv /tmp/spooldir2/.bb.txt /tmp/spooldir2/bb.txt
After few mins
echo "IBM, 100.2, 20160104" >> /tmp/spooldir2/.dr.txt
echo "IBM, 103.1, 20160105" >> /tmp/spooldir2/.dr.txt
mv /tmp/spooldir2/.dr.txt /tmp/spooldir2/dr.txt
You have been given below directory location (if not available than create it) /tmp/spooldir2 .
As soon as file committed in this directory that needs to be available in hdfs in /tmp/flume/primary as well as /tmp/flume/secondary location.
However, note that/tmp/flume/secondary is optional, if transaction failed which writes in this directory need not to be rollback.
Write a flume configuration file named flumeS.conf and use it to load data in hdfs with following additional properties .

1. Spool /tmp/spooldir2 directory
2. File prefix in hdfs sholuld be events
3. File suffix should be .log
4. If file is not committed and in use than it should have _ as prefix.
5. Data should be written as text to hdfs

Problem Scenario 83 : In Continuation of previous question, please accomplish following activities.

1. Select all the records with quantity >= 5000 and name starts with 'Pen'
2. Select all the records with quantity >= 5000, price is less than 1.24 and name starts with
'Pen'
3. Select all the records witch does not have quantity >= 5000 and name does not starts
with 'Pen'
4. Select all the products which name is 'Pen Red', 'Pen Black'
5. Select all the products which has price BETWEEN 1.0 AND 2.0 AND quantity
BETWEEN 1000 AND 2000.

Problem Scenario 82 : You have been given table in Hive with following structure (Which you have created in previous exercise).
productid int code string name string quantity int price float
Using SparkSQL accomplish following activities.

1. Select all the products name and quantity having quantity <= 2000
2. Select name and price of the product having code as 'PEN'
3. Select all the products, which name starts with PENCIL
4. Select all products which "name" begins with 'P\ followed by any two characters,
followed by space, followed by zero or more characters

Problem Scenario 20 : You have been given MySQL DB with following details.
user=retail_dba
password=cloudera
database=retail_db
table=retail_db.categories
jdbc URL = jdbc:mysql://quickstart:3306/retail_db
Please accomplish following activities.

1. Write a Sqoop Job which will import "retaildb.categories" table to hdfs, in a directory
name "categories_targetJob".

Problem Scenario 59 : You have been given below code snippet.
val x = sc.parallelize(1 to 20)
val y = sc.parallelize(10 to 30) operationl
z.collect
Write a correct code snippet for operationl which will produce desired output, shown below. Array[lnt] = Array(16, 12, 20, 13, 17, 14, 18, 10, 19, 15, 11)
