scala shell not part of 1.14.4 download

Hi,

https://nightlies.apache.org/flink/flink-docs-release-1.14/docs/deployment/repls/scala_shell/
mentions:

bin/start-scala-shell.sh local

a script to start a scala REPL shell.

But the download for Flink
https://www.apache.org/dyn/closer.lua/flink/flink-1.14.4/flink-1.14.4-bin-scala_2.12.tgz

Does not seem to include this script anymore.

Am I missing something?

How can I still start a scala repl?

Best,

Georg

Hi Georg，

You can try Zeppelin 0.10.1 which supports scala 2.12 for
Flink interpreter. Internally, Flink interpreter of Zeppelin use scala
shell, you can write scala code and run it in an interactive way.

Hi Georg,

As far as I know, there has never been a Scala Shell for Scala 2.12 because
it was not supported, only for Scala 2.11. The Scala Shell also also been
completely dropped with Flink 1.15.

Best regards,

Martijn

Hi Georg,

I just noticed that the replies between Jeff and me didn't go through the
mailing list. For reference, Jeff moved it to
https://github.com/zjffdu/flink-scala-shell

Many thanks.

In the linked discussion it sounds like a move - not a delete. However, no
destination is named. Is there currently any moved version of the scala
shell available elsewhere?

Best,
Georg

Many thanks.
I will try your suggestions in the coming days.
Why is support for the scala-shell dropped in 2.12? Other projects i.e.
spark also managed to keep a spark-shell (REPL like flink's current
scala-shell) working for the 2.12 release.

Best,
Georg

The Scala Shell only works with Scala 2.11. You will need to use the 
Scala 2.11 Flink distribution.
