Zhan Zhang commented on HBASE-15572: ------------------------------------ [~WeiqingYang] Can you please add a description in the ./src/main/asciidoc/_chapters/spark.adoc as requested. [~busbey] There is a document JIRA opened for the new Dataframe user interface and features. The PR is not sent yet, because currently there is still a number of place needed to be changed in the DataFrame support for HBase. Once it is done, a more complete doc will be sent for the community review. To make the work more trackable, I create a link for this jira to https://issues.apache.org/jira/browse/HBASE-14789.
