Package io.hgraphdb.giraph.utils

Class InternalHBaseVertexRunner

java.lang.Object

io.hgraphdb.giraph.utils.InternalHBaseVertexRunner

public class InternalHBaseVertexRunner
extends Object

A base class for running internal tests on a vertex

Extending classes only have to invoke the run() method to test their vertex. All data is written to a local tmp directory that is removed afterwards. A local zookeeper instance is started in an extra thread and shutdown at the end.

Heavily inspired from Apache Mahout's MahoutTestCase

run

public static Iterable<String> run(org.apache.giraph.conf.GiraphConfiguration conf)
                            throws Exception

Attempts to run the vertex internally in the current JVM, reading from and writing to a temporary folder on local disk. Will start its own zookeeper instance.

Parameters:

conf - GiraphClasses specifying which types to use

Returns:

linewise output data, or null if job fails

Throws:

Exception - if anything goes wrong

run

public static Iterable<String> run(org.apache.giraph.conf.GiraphConfiguration conf,
                                   String checkpointsDir,
                                   File tmpDir)
                            throws Exception

Attempts to run the vertex internally in the current JVM, reading from and writing to a temporary folder on local disk. Will start its own zookeeper instance.

Parameters:

conf - GiraphClasses specifying which types to use

checkpointsDir - if set, will use this folder for storing checkpoints.

tmpDir - file path for storing temporary files.

Returns:

linewise output data, or null if job fails

Throws:

Exception - if anything goes wrong
