ailed to find data source: com.github.saurfang.sas.spark.

[aharre]

I'm getting a similar error to another (now closed) issue, on two different computers, connected to different internet connections.

I've used ´spark_read_sas´ with no issues (Spark 2.0.0) the past two days, but now I'm consequently getting this error. On your example and on my own data.

Looks like an issue, but I can be wrong.

Solved:

1. Connecting to a different version of the Spark server and back again solved the issue for now.

2. Suddenly working on my second computer as well. Some network issue somewhere? (Even if I tried to use three different connections)
