Running Apache MXNet Deep Learning on YARN 3.1 - HDP 3.0

92513-yarnoverview.png

With Hadoop 3.1 / HDP 3.0, we can easily run distributed classification, training and other deep learning jobs. I am using Apache MXNet with Python. You can also do TensorFlow or Pytorch.

If you need GPU resources, you can specify them as such:

yarn.io/gpu=2

My cluster does not have an NVidia GPU unfortunately.

Script:

yarn jar /usr/hdp/current/hadoop-yarn-client/hadoop-yarn-applications-distributedshell.jar -jar /usr/hdp/current/hadoop-yarn-client/hadoop-yarn-applications-distributedshell.jar -shell_command python3.6 -shell_args "/opt/demo/ApacheDeepLearning101/analyzex.py /opt/demo/images/201813161108103.jpg" -container_resources memory-mb=512,vcores=1

For pre-HDP 3.0, see my older script using the DMLC YARN runner. We don't need that anymore. No Spark either.

Python MXNet Script:

https://github.com/tspannhw/ApacheDeepLearning101/blob/master/analyzehdfs.py

Since we are distributed, let's write the results to HDFS. We can use and install the Python HDFS library that works on Python 2.7 and 3.x. So let's pip install it.

pip install hdfs

In our code:

from hdfs import InsecureClient
client = InsecureClient('http://princeton0.field.hortonworks.com:50070', user='root')

from json import dumps
client.write('/mxnetyarn/' + uniqueid + '.json', dumps(row))

We write our row as JSON to HDFS.

When the job completes in YARN, we get a new JSON file written to HDFS.

hdfs dfs -ls /mxnetyarn 

Found 2 items 

-rw-r--r--   3 root hdfs        424 2018-09-21 17:50 /mxnetyarn/mxnet_uuid_img_20180921175007.json
