What is HIVE Metastore?
Hive metastore is a vault that stores metadata (segment names, information types, remarks, and so forth) connected with Apache Hive utilizing MySQL or PostgreSQL. This Hive metastore is executed involving tables in a social data set.
For what reason to Use MySQL in Hive as Metastore:
As a matter of course, Hive accompanies derby data set as metastore.
Derby information base can uphold just single dynamic client at a time
Derby isn't suggested underway climate
So the arrangement here is
Use MYSQL as Meta stockpiling at backend to interface various clients with Hive at a time
MYSQL is Best decision for the independent metastore
Instructions to Install and Configure Hive Metastore to MySQL Database
Install MySQL Server
In this step, we will perform two errands
Establishment of mysql-server
Checking the mysql-server and its cycle
Utilizing sudo adept get introduce mysql-server order, we can download mysql server
Introduce MySQL as displayed in the screen capture
Establishment and Configuration of HIVE and MYSQL
After effective establishment at end, MySQL will run as displayed in beneath screen shot
Establishment and Configuration of HIVE and MYSQL
Install MySQL Java Connector
Introducing MySQL Java Connector. This is for java conditions and association reason
Type My Sql - u root - p followed by secret word
Here - u addresses root username , p signifies secret key
Subsequent to entering the above order, the client needs to enter substantial secret phrase and afterward click enter
Then it will go into My Sql shell mode
Create username and secret key
Making username and secret key for My Sql, conceding honors. From the above screen capture, we notice the accompanying. Here we are characterizing 4 properties that could be important to lay out MYSQL as Meta store in Hive
These are as per the following:
This property is for association URL reason. Here we are characterizing Connection URL in this property. It goes about as JDBC association and its addressing metastore area too This property is for Connection driver name. Here mysql.jdbc. Driver is the regarded esteem we need to make reference to in the worth tag This property utilized for characterizing Connection User name. In this, we characterized "hiveguru" as client name This property utilized for referencing Connection Password. In this, we characterized secret word as client secret phrase. When the properties put in hive - site.xml we need to physically save (Ctrl+S) and close the record. Subsequent to shutting this document, we need to make Hive table and actually look at the table subtleties in MySQL stockpiling.
