APACHE KYLIN - Detect bad query

APACHE KYLIN - Detect bad query

I am setting up Apache kylin , i configured all setting now i am and kylin is connected to hive tables. it show bad query detected and below logs continue all day.What could be the possible reason behind it as there is no error showing in log file when i make cube then it hangs in step one , even i run sample.sh that also hangs at cube formation step

Logs are below and these line continue to generate all day
