I see people asking for it? Is it included or is there a reason its bad practice? I must sound like a broken record
So I ended up just doing it. Hopefully it wont bite me in the butt later.
I copied csvrecordreader, add an int skipColumns argument and change code here
for(int var6 = skipColumns; var6 < var5; ++var6) {
String s = var4[var6];
ret.add(new Text(s));
}
same with csvsequencerecordreader
for (int i = skipNumColumns; i < split.length; i++) {
list.add(new Text(split[i]));
}
