This is an example of how to bulk ingest data into accumulo using map reduce.
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. The
first two arguments to all of the commands except for GenerateTestData are the
accumulo instance name, and a comma-separated list of zookeepers.
$ ./bin/accumulo org.apache.accumulo.examples.simple.mapreduce.bulk.SetupTable -i instance -z zookeepers -u username -p password -t test_bulk row_00000333 row_00000666
$ ./bin/accumulo org.apache.accumulo.examples.simple.mapreduce.bulk.GenerateTestData --start-row 0 --count 1000 --output bulk/test_1.txt
$ ./bin/tool.sh lib/examples-simple-*[^cs].jar org.apache.accumulo.examples.simple.mapreduce.bulk.BulkIngestExample -i instance -z zookeepers -u username -p password -t test_bulk bulk tmp/bulkWork
$ ./bin/accumulo org.apache.accumulo.examples.simple.mapreduce.bulk.VerifyIngest -i instance -z zookeepers -u username -p password -t test_bulk --start-row 0 --count 1000
