> When a DML script is executed in standalone mode (e.g., ./runStandaloneSystemML.sh algorithms/datagen/genLinearRegressionData.dml -nvargs numSamples=1000 numFeatures=50 maxFeatureValue=5 maxWeight=5 addNoise=FALSE b=0 sparsity=1000 output=linRegData.csv format=csv), a crc file is created for each file.
> For example, with the above script, the following files were written to the file system:
> linRegData.csv
> .linRegData.csv.crc
> linRegData.csv.mtd
> .linRegData.csv.mtd.crc
> This litters the file system with a lot of basically unnecessary files. If several scripts are executed, the number of crc grows rapidly.
> There should be a mechanism for one of the following:
> 1) don't generate crc files in the first place
> 2) delete generated crc files
> 3) have an option to generate crc files, with option by default set to false
