• Write to OpenTSDB (scala)
• Count messages (python)

Spark

Example of consuming data ingested by Gobblin on a batch basis and producing Parquet datasets, optimized for consumption by Impala.

• Write to parquet format (scala)
• Write to parquet format (python)

Jupyter

Example of a notebook for manipulating network data.

H2O

Application that runs the H2O data science platform as an application on PNDA.

Flink Streaming

• Count Words (scala) Count the words from Socket.
• Count Words (python) Count the words from input file.
• Flink Windows (java) host-network-data-usage illustrating Flink windows, triggers and event processing.
• Count Hashtags (java) specific word count from input file illustrating metrics, counters and accumulators.

Compound Packages

An example of a package containing multiple application component types, in this case a Spark app and related Jupyter notebook.
