- Tsim ib phau ntawv teev npe rau kev tshwm sim hauv DSEFS cov ntaub ntawv system: dse hadoop fs -mkdir /spark $ dse hadoop fs -mkdir /spark/events.
- Thaum qhib qhov kev tshwm sim, qhov kev coj cwj pwm tsis zoo yog rau txhua lub cav kom tau txais kev cawmdim, uas ua rau kev cia khoom loj tuaj raws sijhawm.
