Q:

Couldn't find hbase jar on eclipse

I want to run a simple program on hbase by eclipse and following step on:  
https://www.guru99.com/handling-tables-hbase.html 
but when I add external jar on myself, hbase-version.jar and hadoop-version-core.jar isn't in my /hbase/lib
Are these two jars important? 
Where can I get those two jars?

A:

You can get the hadoop core jar maven repository and hbase jar maven repository
[or]
Please convert your project to maven.
In pom.xml add the below dependencies
Hadoop Core jar
<!-- https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-core -->
<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-core</artifactId>
    <version>1.2.1</version>
</dependency>

HBase jar
<!-- https://mvnrepository.com/artifact/org.apache.hbase/hbase -->
<dependency>
    <groupId>org.apache.hbase</groupId>
    <artifactId>hbase</artifactId>
    <version>0.92.1</version>
</dependency>

Yes, both jars are important. Hadoop core jar contains the core apis like TaskTracker, JobTracker, InputSplit etc.
HBase jar contains core apis like zookeeper, rest, thrift, mapreduce etc.
