Run Husky on Yarn

Husky on Yarn

Make Husky run on YARN.

Dependencies

• Java 1.7+
• Maven 3.3.9
• Hadoop 2.6+

Usage

One can use run.sh to run a husky application on yarn:

run.sh /path/to/master /path/to/app /path/to/config

This script will first build this project and submit a job to yarn.

Before running run.sh, please ensure that you've built husky master and application (see details), and prepared a nice config file. master_port and comm_port must be provided by the config file. See an example below:

# Required
master_port=yyyyy
comm_port=yyyyy

# Optional
hdfs_namenode=xxx.xxx.xxx.xxx
hdfs_namenode_port=yyyyy

By default, run.sh creates two one worker node, which contains two workers, on localhost to run the application. This can be changed by modifying --worker.info in run.sh.
