h2o.import_hive_table

Import Hive table to H2OFrame in memory.
Make sure to start H2O with Hive on classpath. Uses hive-site.xml on classpath to connect to Hive.
When database is specified as jdbc URL uses Hive JDBC driver to obtain table metadata. then 
uses direct HDFS access to import data.

R interface for 'H2O', the scalable open source machine learning
platform that offers parallelized implementations of many supervised and
unsupervised machine learning algorithms such as Generalized Linear
Models (GLM), Gradient Boosting Machines (including XGBoost), Random Forests,
Deep Neural Networks (Deep Learning), Stacked Ensembles, Naive Bayes,
Generalized Additive Models (GAM), ANOVA GLM, Cox Proportional Hazards, K-Means, PCA, ModelSelection,
Word2Vec, as well as a fully automatic machine learning algorithm (H2O AutoML).
