Hadoop - waiting for AM container to be allocated, launched and register with RM

Dear All,

I install an insight into edx native. Installation was successful but when I import database table as “remote-task --host localhost --user root --remote-name analyticstack --skip-setup --wait ImportEnrollmentsIntoMysql --interval 2019-06-01 --overwrite-n-days 3 --local-scheduler”. I face Hadoop error as the following screenshot and there are too many pending jobs. How can I solve this? Thanks.
