Domain-specific language for graph processing: Create a GraphDataSet that
abstracts away the internal representation of a graph and operations on the
GraphDataSet. The project involves gathering requirements for graph
processing functionality, architecting the DSL, implementation, and
possible work on optimizing the operations when a graph operation can be
mapped to different DataSet to DataSet transformations.
Distributed mutable state: Currently delta iterations use internally a hash
index to store the state of the iteration, and they invoke index merging
functionality. One idea would be to surface an operator (with care) to the
APIs that essentially allows mutable state manipulations. Another idea
would be to implement something along the lines of a parameter server and
make such functionality accessible to the APIs.
Domain-specific language for spatial data: Create spatial data types
(point, region, etc) and operations thereof
Integration into Apache BigTop
Integration with Apache Ambari
Pig frontend for Flink: An initial effort was here:

Cascading on Flink
Optimizing the integration with columnar file formats (Parquet, ORCFile)
and perhaps eventually pushing filters down to data scans.
Statistical operators to extract statistical information from a DataSet
(e.g., histograms of value distributions)
Integration with Apache Mahout (ongoing effort)
Integration with Apache Tez (ongoing effort)
Flink Streaming (ongoing effort)
