> Problem with field separator in FieldSelectionHelper
> ----------------------------------------------------
>
> Key: MAPREDUCE-5121
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5121
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 1.0.4

> I found that org.apache.hadoop.mapreduce.lib.fieldsel.FieldSelectionHelper
> and the corresponding old api
> org.apache.hadoop.mapred.lib.FieldSelectionMapReduce take user specified
> separator string as a regular expression in String.split(), but also use it
> as a normal string in StringBuffer.append(). It will be a problem if the
> separator string contains meta character. I suggest take separator literally
> by calling Pattern.quote(separator). Or just use another property to specify
> the separator which should be added in the output.
