reddycharan opened a new issue #1495: provide option to enforce minNumRacksPerWriteQuorum
URL: https://github.com/apache/bookkeeper/issues/1495
 
 
   **FEATURE REQUEST**
   
   1. Please describe the feature you are requesting.
   
   https://github.com/apache/bookkeeper/pull/1397 introduces feature to have bookies from "minNumRacksPerWriteQuorum" number of racks per writequorum, instead of just 2 racks. But it doesn't enforces 'minNumRacksPerWriteQuorum" number of racks. If it cann't find a bookie to honor minNumRacksPerWriteQuorum then it will fallback to random. So we need an option to enforce the guarantee of minNumRacksPerWriteQuorum if it is enabled. If it cann't find a bookie to enforce the guarantee then the API in RackawareEnsemblePlacementPolicy should throw BKNotEnoughBookiesException.
   
   2. Indicate the importance of this issue to you (blocker, must-have, should-have, nice-to-have). Are you currently using any workarounds to address this issue?
   
   It is kind of must-have feature for our uses-case to provide durability guarantee across the faultzones (racks).
