  12. def escapeForShell(arg: String): String

    Escapes a string for inclusion in a command line executed by Yarn.

    Escapes a string for inclusion in a command line executed by Yarn. Yarn executes commands using either

    (Unix-based) bash -c "command arg1 arg2" and that means plain quoting doesn't really work. The argument is enclosed in single quotes and some key characters are escaped.

    (Windows-based) part of a .cmd file in which case windows escaping for each argument must be applied. Windows is quite lenient, however it is usually Java that causes trouble, needing to distinguish between arguments starting with '-' and class names. If arguments are surrounded by ' java takes the following string as is, hence an argument is mistakenly taken as a class name which happens to start with a '-'. The way to avoid this, is to surround nothing with a ', but instead with a ".

    arg

    A single argument.

    returns

    Argument quoted for execution via Yarn's generated shell script.

  13. def executorOffHeapMemorySizeAsMb(sparkConf: SparkConf, execRequest: ExecutorResourceRequest): Long
