Read CSV file and delete hdfs, hive and hbase tables
I have a CSV file with hdfs directories, hive tables and hbase tables.
1. first column - hdfs directories
2. second column - hive tables
3. third column - hbase tables
I have to check the csv file and look for the first column and delete the hdfs directory from the hdfs path, now search for the second column and delete the hive table, after that look for third column and delete the hbase table.
appreciate your help.

DTIF(5) File Formats Manual DTIF(5)
Name
DTIF - Digital Table Interchange Format
Description
Digital Table Interchange Format (DTIF) is the standard format for the storage and interchange of documents that contain data tables, for-
mulas, and spreadsheets. You can use DTIF to store and retrieve database information, interchange spreadsheets, and reference table data in
compound documents.
DTIF defines the logical structure and physical layout of a data table, the values within the table (absolute data and/or expressions), and
presentation attributes (formatting) to be used when displaying or printing the table. DTIF works with Digital Document Interchange Format
(DDIF) so that you can store or reference DTIF tables in DDIF-encoded compound documents.
A DTIF document can contain a sequence of one or more tables and is uniquely identified by a product name, a version number, and other
descriptive information such as the document's title and creation date. Each DTIF table is a 2-dimensional display of data values orga-
nized in columns and rows that has its own structure and table data stored in cells.
In DTIF documents, attributes specify the type and format of information pertaining to the data stored in a table. Column attributes
describe information for all the cells in a particular column, whereas generic column attributes can be applied to any column in any table
that references them. Format attributes define the printed and displayed presentation of data stored in the table. Format attributes can
also be redefined at the window, column, or cell level.
