    I have a hack, what if instead of 
    `wget -q 
http://mirror.tcpdiag.net/apache/spark/spark-1.6.0/spark-1.6.0-bin-hadoop2.3.tgz`
    
    we use
    
        wget -q -r -np -N   
http://mirror.tcpdiag.net/apache/spark/spark-1.6.0/spark-1.6.0-bin-hadoop2.3.tgz
 &
        wget -q -r -np -N   
http://mirror.tcpdiag.net/apache/spark/spark-1.6.0/spark-1.6.0-bin-hadoop2.3.tgz
 &
        wget -q -r -np -N   
http://mirror.tcpdiag.net/apache/spark/spark-1.6.0/spark-1.6.0-bin-hadoop2.3.tgz
 &
        wget -q -r -np -N   
http://mirror.tcpdiag.net/apache/spark/spark-1.6.0/spark-1.6.0-bin-hadoop2.3.tgz
 &
        wget -q -r -np -N   
http://mirror.tcpdiag.net/apache/spark/spark-1.6.0/spark-1.6.0-bin-hadoop2.3.tgz
    
    Which will make wget download using 5 simultaneous connections, which may 
result in downloading it quicker.
    
    or
    
        THREADS=5
        WGETFLAGS=’-r -np -N’
        
URL="http://mirror.tcpdiag.net/apache/spark/spark-1.6.0/spark-1.6.0-bin-hadoop2.3.tgz";
        for i in `seq 1 $((THREADS-1))`
        do
          Command=”$Command””wget $WGETFLAGS $URL”‘ & ‘
        done
        Command=”$Command””wget $WGETFLAGS $URL”
        eval $Command
