IntegrationTestMapReduce (Apache Accumulo Testing 1.10.3 API)

java.lang.Object
- org.apache.hadoop.conf.Configured
- - org.apache.accumulo.test.mrit.IntegrationTestMapReduce

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool
```
public class IntegrationTestMapReduce
extends org.apache.hadoop.conf.Configured
implements org.apache.hadoop.util.Tool
```
Run the Integration Tests as a Map-Reduce job.
Each of the Integration tests takes 30s to 20m to run. Using a larger cluster, all the tests can be run in parallel and finish much faster.
To run the tests, you first need a list of the tests. A simple way to get a list, is to scan the accumulo-test jar file for them.
```
 $ jar -tf lib/accumulo-test.jar | grep IT.class | tr / . | sed -e 's/.class$//' >tests
 
```
Put the list of tests into HDFS:
```
 $ hadoop fs -mkdir /tmp
 $ hadoop fs -put tests /tmp/tests
 
```
Run the class below as a map-reduce job, giving it the lists of tests, and a place to store the results.
```
 $ yarn jar lib/accumulo-test-mrit.jar -libjars lib/native/libaccumulo.so /tmp/tests /tmp/results
 
```
The result is a list of IT classes that pass or fail. Those classes that fail will be annotated with the particular test that failed within the class.
