Tristan, thanks for adding it on your list.   JDBC is indeed something that users will be able to do without admin intervention. That should help us out in the meantime. Within the R/tidyverse, the odbc package is becoming popular and although it still has few problems we are pushing users to use that approach.   Within the context of making Impala available to CDSW users, would it be possible to preconfigure the container impala-shell with the cluster info? It's a small thing and we can specify all the info when using it, but explaining all that to users takes focus and time away on getting things done. In our case we will also use impala-shell in a small internal package to allow transfer of data from R back to an Impala table with a single function.   Thanks! Bruno ... View more
