Hive Create Table

Table Operations like Creation, Altering, and Dropping tables in Hive can be seen in this instructional exercise. In the underneath screen capture, we are making a table with segments and modifying the table name. Making table guru_sample with two section names, for example, "empid" and "empname"

Showing tables present in data set

sample showing under tables

Changing table "guru_sample" as "guru_sampleNew"

Once more, when you execute "show" order, it will show the new name Guru_sampleN

Table sorts and its Usage:

Inner tables

Inner Table is firmly coupled in nature. In this kind of table, first we need to make table and burden the information.

We can call this one as information on outline.

By dropping this table, the two information and composition will be eliminated.

The put away area of this table will be at/client/hive/stockroom.

When to Choose Internal Table?

In the event that the handling information accessible in nearby document framework

Assuming that we believe Hive should deal with the total lifecycle of information including the cancellation

Assuming you dropped the guruhive_internaltable, including its metadata and its information will be erased from Hive.

From the accompanying screen capture, we can notice the result

Information activities in Hive

In above code and from screen capture we do following things,

Make the inner table

Load the information into inner table

Show the substance of the table

To drop the inner table

Outside tables

Outside Table is approximately coupled in nature. Information will be accessible in HDFS. The table will make on HDFS information.

In alternate manner, we can say like its making construction on information.

At the hour of dropping the table it drops just diagram, the information will be as yet accessible in HDFS as in the past.

Outside tables give a choice to make various blueprints for the information put away in HDFS as opposed to erasing the information each time at whatever point diagram refreshes

When to Choose External Table?

On the off chance that handling information accessible in HDFS

Helpful when the records are being utilized beyond Hive
