The ability to embed Python, Javascript and R code within ECL, and to call external Java code simply from ECL programs;

Eclipse Language Plugin gold version which adds ECL awareness and HPCC Systems Platform integration to the Eclipse IDE allowing the user to manage the entire ECL life cycle from remotely writing and syntax checking ECL to submitting and monitoring ECL Workunits on the HPCC Systems Platform all from within the Eclipse IDE;

1,Provide more detailed docs about architecture and it's implementation

You guys provided some docs,and few of them talk about architecture:what components exists primarily,but they can be taken as brief introductions only.What we really want to get are tow docs about:1,calculation model introduction,like google's paper's did;2,implementation details, like chapters 1~8 of <<Hadoop:The Definitive Guide>> did.If these cost time.would you please provide two detailed docs about 1, Detailed component's functions(Some thing can be found on wp_introduction_HPCC.pdf,but it is too simple) introduction; 2, Typical work-flow introduction:how and where data is prepared,distributed and computed and collected,by who and what format.These two will help CIO/CTOs to make decision from deeper level.

2,Don't take too much energy on java.

Java can decrease development cost but increase running cost.For not so large system,it is worth using it,but for larges,cost equation: x*RC+y*DC=TC(here,RC=running cost,dc=develop cost,tc=total cost,x=server count,y=developer count) changed.So when we start our own business,we try our best to de-javaing,use golang(it is growing quickly) as server side language and try different computing frameworks.Most of our members have >8 years experience on java,and after one week,we are all quite comfortable with ecl,so client language is a problem,but not so big. By the way,you can't use java to beat a java based ecosystem, but better focusing on you own strengths:better performance,make it "more" better.And maturity,your IDE,configuration and management tools are quite good.

2,No (dedicated) docs to talk about how to develop plugins for HPCC.

If you want to an ecosystem,you need plugins.So if possible,provide a good doc on plugin development.

3,Provide html based doc.
