Description

It seems that during one of the previous merge some unnecessary spaces has been added to the hadoop-hdfs-project/hadoop-hdfs/src/main/bin/hdfs file.

After a dist build I can not start server with the hdfs command:

/tmp/hadoop-3.1.0-SNAPSHOT/bin/../libexec/hadoop-functions.sh: line 398: syntax error near unexpected token `<'
/tmp/hadoop-3.1.0-SNAPSHOT/bin/../libexec/hadoop-functions.sh: line 398: `  done < <(for text in "${input[@]}"; do'

See the space at here:

To be honest I don't understand how it could work for others, as it seems to be an older change. Maybe some git magic removed it on OSX (I use linux). Anyway I upload a patch to fix it.
