The scalability test framework needs to be configured for your Accumulo instance by performing the following steps.
WARNING: Each scalability test rewrites your conf/tservers file and reinitializes your Accumulo instance. Do not run these tests on a cluster holding essential data.
Make sure you have both ACCUMULO_HOME and HADOOP_HOME set in your $ACCUMULO_CONF_DIR/accumulo-env.sh.
Edit the ‘site.conf’ file in the conf directory containing settings needed by test nodes to connect to Accumulo, and to guide the tests.
$ vim conf/site.conf
Edit the ‘Ingest.conf’ file in the conf directory containing performance settings for the Ingest test. (This test is currently the only scalability test available.)
$ vim conf/Ingest.conf
Each test has a unique ID (e.g., “Ingest”) which correlates with its test code in:
org.apache.accumulo.test.scalability.tests.<ID>
This ID correlates with a config file:
conf/<ID>.conf
To run the test, specify its ID to the run.py script.
$ nohup ./run.py Ingest > test1.log 2>&1 &
A timestamped directory will be created, and results are placed in it as each test completes.
