i have question about stoping the optimizers when the ams server stopped. As i know,ams has ha, i assume when all ams server stopped then we can stop optimizers.

want to add stop-all.sh & start-all.sh

@klion26 could you help to check？ if match you design， i will do more testing

when i rum TestDefaultOptimizingService，testPollTaskTwice is error。 i cannot reproduce errors that you mentioned

is it fixed now？if not plz assign to me

@zhoujinsong plz assign to me

@zhoujinsong zhou code coverage checking is error， do you know anyone who can fix it

Is it means when table is dropped， it should clean all optimizing data immediately. In addition, we should remove table history recorders in database which cannot find table name in...

plz assign this issue to me

I will submit pr next weekend
