This tutorial uses the following Java classes, which can be found in org.apache.accumulo.examples.simple.helloworld in the examples-simple module:
* - Inserts 10K rows (50K entries) into accumulo with each row having 5 entries
* - Reads all data between two rows
Log into the accumulo shell:
$ ./bin/accumulo shell -u username -p password
Create a table called 'hellotable':
username@instance> createtable hellotable
Launch a Java program that inserts data with a BatchWriter:
$ ./bin/accumulo org.apache.accumulo.examples.simple.helloworld.InsertWithBatchWriter -i instance -z zookeepers -u username -p password -t hellotable
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
To view the entries, use the shell to scan the table:
username@instance> table hellotable
username@instance hellotable> scan
You can also use a Java class to scan the table:
$ ./bin/accumulo org.apache.accumulo.examples.simple.helloworld.ReadData -i instance -z zookeepers -u username -p password -t hellotable --startKey row_0 --endKey row_1001
