kandi X-RAY | Dsl.scala Summary

Dsl.scala is a Scala library typically used in Programming Style, Functional Programming applications. Dsl.scala has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Dsl.scala is a framework to create embedded Domain-Specific Languages in Scala. It can be considered as an alternative syntax to for comprehension, Scala Async and Scala Continuations. It unifies monads, generators, asynchronous functions, coroutines and continuations to a single universal syntax, and can be easily integrate to Scalaz, Cats, Scala Collections, Scala Futures, Akka HTTP, Java NIO, or your custom domains. A DSL author is able to create language keywords by implementing the Dsl trait, which contains only one abstract method to be implemented. No knowledge about Scala compiler or AST macros is required. DSLs written in Dsl.scala are collaborative with others DSLs and Scala control flows. A DSL user can create functions that contains interleaved DSLs implemented by different vendors, along with ordinary Scala control flows.

You should use a full test name. testOnly some.package.name.TestName or testOnly *TestName.

This error occurs when GC takes up over 98% of the total execution time of process. You can monitor the GC time in your Spark Web UI by going to stages tab in http://master:4040.

Try increasing the driver/executor(whichever is generating this error) memory using spark.{driver/executor}.memory by --conf while submitting the spark application.

Another thing to try is to change the garbage collector that the java is using. Read this article for that: https://databricks.com/blog/2015/05/28/tuning-java-garbage-collection-for-spark-applications.html. It very clearly explains why GC overhead error occurs and which garbage collector is best for your application.

ANSWER

Scala does not have binary compatibility across major releases (and 2.11.x is a different major release from 2.12.x).

This means that you absolutely cannot use a library compiled against Scala 2.11 in a project that uses Scala 2.12, sorry.

You might want to:

Downgrade your project by setting scalaVersion := "2.11.11"
Wait for cronish to release a version compiled against Scala 2.12
Try to compile cronish against Scala 2.12 (if you e.g. host a fork on github, it is possible to depend on it directly by URL in your build.sbt)

No vulnerabilities reported

Install Dsl.scala

Suppose you want to create a random number generator. The generated numbers should be stored in a lazily evaluated infinite stream, which can be built with the help of our built-in domain-specific keyword Yield.
