Now write a flume configuration file named flume3.conf, using that configuration file dumps logs in HDFS file system
in a directory called flumeflume3/%Y/%m/%d/%H/%M
Means every minute new directory should be created). Please us the interceptors to provide timestamp information, if
message header does not have header info.
And also note that you have to preserve existing timestamp, if message contains it. Flume channel should have
following property as well. After every 100 message it should be committed, use non-durable/faster channel and it

Question: 104
Now import data from mysql table departments to this hive table. Please make sure that data should be visible using
below hive command, select" from departments_hive
Answer: Solution:
Step 1: Create hive table as said.
hive
show tables;
create table departments_hive(department_id int, department_name string);
Step 2: The important here is, when we create a table without delimiter fields. Then default delimiter for hive is ^A
(01). Hence, while importing data we have to provide proper delimiter.
sqoop import
-connect jdbc:mysql://quickstart:3306/retail_db
~username=retail_dba
-password=cloudera
�table departments
�hive-home /user/hive/warehouse
-hive-import
-hive-overwrite
�hive-table departments_hive
�fields-terminated-by �01�
Step 3: Check-the data in directory.
hdfs dfs -Is /user/hive/warehouse/departments_hive
hdfs dfs -cat/user/hive/warehouse/departmentshive/part�
Check data in hive table.
Select * from departments_hive;
Question: 105
Import departments table as a text file in /user/cloudera/departments.
Answer: Solution:
Step 1: List tables using sqoop
sqoop list-tables �connect jdbc:mysql://quickstart:330G/retail_db �username retail dba -password cloudera
Step 2: Eval command, just run a count query on one of the table.
sqoop eval
�connect jdbc:mysql://quickstart:3306/retail_db
-username retail_dba
-password cloudera
�query "select count(1) from ordeMtems"
Step 3: Import all the tables as avro file.
sqoop import-all-tables
-connect jdbc:mysql://quickstart:3306/retail_db
-username=retail_dba
-password=cloudera
-as-avrodatafile
-warehouse-dir=/user/hive/warehouse/retail stage.db
-ml
Step 4: Import departments table as a text file in /user/cloudera/departments
sqoop import
-connect jdbc:mysql://quickstart:3306/retail_db
-username=retail_dba
-password=cloudera
-table departments
-as-textfile
-target-dir=/user/cloudera/departments
Step 5: Verify the imported data.
hdfs dfs -Is /user/cloudera/departments
hdfs dfs -Is /user/hive/warehouse/retailstage.db
hdfs dfs -Is /user/hive/warehouse/retail_stage.db/products
Question: 106
Problem Scenario 2:
There is a parent organization called "ABC Group Inc", which has two child companies named Tech Inc and MPTech.
Both companies employee information is given in two separate text file as below. Please do the following activity for
employee details.
Tech Inc.txt
Answer: Solution:
Step 1: Check All Available command hdfs dfs
Step 2: Get help on Individual command hdfs dfs -help get
Step 3: Create a directory in HDFS using named Employee and create a Dummy file in it called e.g. Techinc.txt hdfs
dfs -mkdir Employee
Now create an emplty file in Employee directory using Hue.
Step 4: Create a directory on Local file System and then Create two files, with the given data in problems.
Step 5: Now we have an existing directory with content in it, now using HDFS command line, overrid this existing
Employee directory. While copying these files from local file System to HDFS. cd /home/cloudera/Desktop/ hdfs dfs -
put -f Employee
Step 6: Check All files in directory copied successfully hdfs dfs -Is Employee
Step 7: Now merge all the files in Employee directory, hdfs dfs -getmerge -nl Employee MergedEmployee.txt
Step 8: Check the content of the file. cat MergedEmployee.txt
Step 9: Copy merged file in Employeed directory from local file ssytem to HDFS. hdfs dfs -put MergedEmployee.txt
Employee/
Step 10: Check file copied or not. hdfs dfs -Is Employee
Step 11: Change the permission of the merged file on HDFS hdfs dfs -chmpd 664 Employee/MergedEmployee.txt
Step 12: Get the file from HDFS to local file system, hdfs dfs -get Employee Employee_hdfs
Question: 107
Problem Scenario 30: You have been given three csv files in hdfs as below.

E09, 10000
E10, 10000
Answer: Solution:
Step 1: Create all three files in hdfs in directory called sparkl (We will do using Hue}. However, you can first create in
local filesystem and then
Step 2: Load EmployeeManager.csv file from hdfs and create PairRDDs
val manager = sc.textFile("spark1/EmployeeManager.csv")
val managerPairRDD = manager.map(x=> (x.split(", ")(0), x.split(", ")(1)))
Step 3: Load EmployeeName.csv file from hdfs and create PairRDDs
val name = sc.textFile("spark1/EmployeeName.csv")
val namePairRDD = name.map(x=> (x.split(", ")(0), x.split(�")(1)))
Step 4: Load EmployeeSalary.csv file from hdfs and create PairRDDs
val salary = sc.textFile("spark1/EmployeeSalary.csv")
val salaryPairRDD = salary.map(x=> (x.split(", ")(0), x.split(", ")(1)))
Step 4: Join all pairRDDS
val joined = namePairRDD.join(salaryPairRDD}.join(managerPairRDD}
