i do some INSERT ,because i will do some scan operations, i use the OrderPreservingPartition method.
the state of the cluster is showed below. as i predicated the load is very imbalance, and some of the nodes down (in some nodes,the Cassandra processes died and in others the processes are alive but they still down), so i have two questions: 1)how to do balance after the insert ends? 2)why the nodes died? how to make them up again (when the situation is that the process is alive but the node'state is down) thx 10.37.17.241 Up 47.65 GB 0p6ovvUXMJ4cdd1L |<--| 10.37.17.234 Up 67.41 GB 5OxiS2DKBZLeISPg | ^ 10.37.17.235 Up 67.54 GB 7UDcS0SToePuQACe v | 10.37.17.246 Up 555 bytes OCvC3nqKLeKA5n0I | ^ 10.37.17.233 Up 830 bytes SJp6cQRNox52av2Y v | 10.37.17.249 Up 830 bytes SxVmCVcruOpoS48B | ^ 10.37.17.247 Up 555 bytes TGctCMvfNuRo7RjS v | 10.37.17.245 Up 555 bytes j2smY0OOtQ0SeeHY | ^ 10.37.17.250 Up 830 bytes jNwBPchW58i5tGxp v | 10.37.17.248 Up 830 bytes jYWaJC93OyMdWDaN | ^ 10.37.17.237 Up 830 bytes mPwhLOsKlbPart6j v | 10.37.17.236 Up 830 bytes noh0t8HJgw4hmz7I | ^ 10.37.17.244 Up 555 bytes q8c8SPYEkWEzmFcR v | 10.37.17.238 Up 555 bytes rIuuq3AR4DVK989X | ^ 10.37.17.242 Up 555 bytes smebTmIvQBMG56Zf v | 10.37.17.243 Up 555 bytes tWTYyiqAKQVw7197 | ^ 10.37.17.232 Up 830 bytes uVdBQkR9Dszm5deK v | 10.37.17.239 Up 555 bytes xXQkDQn1vvg8e1xS | ^ 10.37.17.240 Up 555 bytes yQRrq9RG2dUsHUyR |-->| -- Bingbing Liu Web and Mobile Data Management lab Renmin University of China
