Saving reactive datatable from Shiny R webapp into HDFS dataset

Marija

Hi all,

I am able to use function dkuReadDataset in Shiny R webapp without problems, but I have troubles when I try to save the reactive datatable df() (or even not reactive).

I have made a dataset "test" inside of flow. But still when I run dkuWriteDataset(df(), "test"), the screen becomes grey in Shiny.

It would be the best if I could append the data each time user clicks in webapp some filter etc.

Thank you so much in advance,

Marija
