But only for SDK write with string(old way). It no need decode if user write with real data type, like byte[]. I changed just now. removed Hex.decodeHex. So user will get hex code from read when user want to encode binary to hex and write to csv file. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
