Apache Accumulo Hello World Example

This tutorial uses the following Java classes:

• Insert.java - Inserts 10K rows (50K entries) into accumulo with each row having 5 entries
• Read.java - Reads data between two rows

Inserts data with a BatchWriter:

$ ./bin/runex helloworld.Insert

On the accumulo status page at the URL below (where ‘master’ is replaced with the name or IP of your accumulo master), you should see 50K entries

http://master:9995/

To view the entries, use the shell (run accumulo shell -u username -p password to access it) to scan the table:

username@instance> table hellotable
username@instance hellotable> scan

You can also use a Java class to scan the table:

$ ./bin/runex helloworld.Read
