> This is SPARK-5931's sister issue.
> The naming of existing byte configs is inconsistent. We currently have the following
throughout the code base:
> {code}
> spark.reducer.maxMbInFlight // megabytes
> spark.kryoserializer.buffer.mb // megabytes
> spark.shuffle.file.buffer.kb // kilobytes
> spark.broadcast.blockSize // kilobytes
> spark.executor.logs.rolling.size.maxBytes // bytes
> spark.io.compression.snappy.block.size // bytes
> {code}
> Instead, my proposal is to simplify the config name itself and make everything accept
time using the following format: 500b, 2k, 100m, 46g, similar to what we currently use for
our memory settings. For instance:
> {code}
> spark.reducer.maxSizeInFlight = 10m
> spark.kryoserializer.buffer = 2m
> spark.shuffle.file.buffer = 10k
> spark.broadcast.blockSize = 20k
> spark.executor.logs.rolling.maxSize = 500b
> spark.io.compression.snappy.blockSize = 200b
> {code}
> All existing configs that are relevant will be deprecated in favor of the new ones. We
should do this soon before we keep introducing more time configs.
