For completeness, there is also an often overlooked until loop in shell.

until [ "$answer" = no ]; do
    echo "Enter the city name"
    read cityname
    echo "Enter the state name"
    read statename
    pig -x mapreduce mb_property_table_updated.pig city=$cityname state=$statename
    echo "Do you want to run for another city"
    read answer
done

I'd do something like this:

while [ "$e" != "n" ]; do
    echo "Enter the city name"
    read cityname
    echo "Enter the state name"
    read statename
    pig -x mapreduce mb_property_table_updated.pig city=$cityname state=$statename
    echo "Do you want to run for another city (y/n)"
    read e
done

use while loop

line=yes
while [ "$line" = yes ]
do
echo "Enter the city name"
read cityname
echo "Enter the state name"
read statename
pig -x mapreduce mb_property_table_updated.pig city=$cityname state=$statename
echo "Do you want to run for another city"
read line
done

And also in for loop

for((;;))
do
echo "Enter the city name"
read cityname
echo "Enter the state name"
read statename
pig -x mapreduce mb_property_table_updated.pig city=$cityname state=$statename
echo "Do you want to run for another city"
read answer
if [ "$answer" = "yes" ]
then
continue
else
break
fi
done
