Apache Accumulo Bulk Ingest Example

This is an example of how to bulk ingest data into Accumulo using map reduce.

This tutorial uses the following Java classes.

• SetupTable.java - creates the table and some data to ingest
• BulkIngestExample.java - ingest the data using map reduce
• VerifyIngest.java - checks that the data was ingested

Remember to copy the accumulo-examples-*.jar to Accumulo's ‘lib/ext’ directory.

$ cp target/accumulo-examples-*.jar /path/accumulo/lib/ext

The following commands show how to run this example. This example creates a table called test_bulk which has two initial split points. Then 1000 rows of test data are created in HDFS. After that the 1000 rows are ingested into Accumulo. Then we verify the 1000 rows are in Accumulo.
