#General Remarks TAP 0.7.2 is a patch release to version 0.7.0 and 0.7.1.

It is not mandatory to upgrade to 0.7.2 from 0.7.0 or 0.7.1.

All GitHub repositories included in this TAP release were tagged with a 0.7.2 tag.

#New Features ##H2O on TAP Open-source big-data analysis software H2O is now available on TAP. Users can run H2O server on YARN with a single mouse click from the TAP Marketplace or Data Science tab.

In the Model Catalog tab, users can see the list of all models created on the H2O server. For every model there is an option to download an executable scoring engine based on the model or publish the model as an offering to TAP Marketplace.

In TAP version 0.7.2, the H2O console temporarily accesses CDH resources as a CF (CloudFoundry) technical user. Starting with the next TAP release, the H2O console will access CDH resources as a regular TAP user.

Visit http://www.h2o.ai/ to learn more about H2O. #Improvements ##Support for Additional SQL Sources for Data Import In addition to PostgreSQL, the data import scheduler now supports importing data from the following databases:

  • MySql
  • Oracle
  • Teradata

##ARIMA Feature Enhancements The following tests are now available to be used with the ARIMA model:

  • Dickey-Fuller test
  • Durbin-Watson test
  • Breusch-Godfrey test
  • Breusch-Pagan

##OrientDB Dashboard The OrientDB dashboard is the advanced web tool for managing OrientDB. This tool is now installed in “trustedanalytics” organization during platform deployment and is bound to the orientdb service. OrientDB dashboard instance is visible in the Applications tab.

Additionally, a dashboard for managing OrientDB is available in the Marketplace tab. Users can create their own dashboard instances in their organization and bind them to the orientdb service instance in the same organization.

##CDH and Spark Upgrade TAP 0.7.2 now supports CDH 5.7, which includes Spark 1.6.

Spark 1.6 updates the functionality of Gaussian Mixture Models (GMM) and Power Iteration Clustering (PIC) substantially; these models will likely not generate the same values as the pre-upgrade models.
