7. 7 © Hortonworks Inc. 2011–2018. All rights reserved. Recommendations • Install CPU Version on CPU YARN Nodes • Install GPU Version on Nvidia (CUDA) • Do training on GPU YARN Nodes where possible • Apply Model on All Nodes and Trigger with Apache NiFi • What helps Hadoop and Spark will help TensorFlow. More RAM, More and Faster Cores, More Nodes. • Today, Run either pure TensorFlow with Keras <or> TensorFlow on Spark. • Try YARN 3.0 Containerized TensorFlow later in the year. • Consider Alluxio or Apache Ignite for in-memory optimization • Download the model zoos • Evaluate other Deep Learning Frameworks like MXNet and PyTorch

9. 9 © Hortonworks Inc. 2011–2018. All rights reserved. TensorFlow on Hadoop https://www.tensorflow.org/deploy/hadoop HDFS files can be used as a distributed source for input producers for training, allowing one fast cluster to Store these massive datasets and share them amongst your cluster. This requires setting a few environment variables: JAVA_HOME HADOOP_HDFS_HOME LD_LIBRARY_PATH CLASSPATH
