            Reporter: yuwenbing
             Fix For: 1.10.1, 1.11.0

generally speaking,if you  execute  the  command  【{{echo 
"flink\npyflink\nflink" > /tmp/input】}}  to prepare input data in the 
"/tmp/input" file ,because of  terminal user's    different version ,it can 
leads different result 。In this case ,in order to make the same wordcount 
result for everyone,so this echo command must be added -e as parameter like 
【{{echo -e "flink\npyflink\nflink" > /tmp/input】}}
