I think for Spark interpreter it can properly process the string interpolation
without any problems caused by dynamic form.

So for spark interpreter does ${x} create a dynamic textbox or is interpreted
as string interpolation? Or is it context-sensitive and knows about s"...."?

But somehow Spark interpreter works without this problem. Why is that the case
if the problem is on Zeppelin UI side?

Yes, this is due to the dynamic forms of zeppelin.

I run into similar issues with shell scripts that use ${var}. Can we use a
different magic notation for Z, one that has a lower chance of colliding with
shell scripts and Scala code? This will be hard to do due to the variety of
interpreters supported. Perhaps this can be made configurable?

Hi,
When writing Spark Scala code in zeppelin with Livy interpreter, string
interpolation does not seem to work. For example:
val devices = sc.objectFile[(VertexId, DeviceAttr)](
s"s3a://${bucket}/${datasetS3Prefix}/${tableName}
/dt=${end_dt}/tid=${tid}/${datasetS3Suffix}")
I think the dollar curly brackets were interpreted as Javascript template
literals and hence disappear when Livy server gets the message and becomes:
val devices = sc.objectFile[(VertexId, DeviceAttr)](
s"s3a://///dt= /tid= / ")
At the same time a couple of input boxes appears at the bottom of this
paragraph in Zeppelin UI having the corresponding titles in the original dollar
curly brackets.
Is this a bug? How can we overcome the string interpolation issue?
Thanks,
Jialiang
