[GitHub] [incubator-uniffle] colinmjj commented on issue #108: [Improvement] `sendCommit` should allow shuffle servers dead under the condition of ensuring data integrity

   > I found if use `MEMORY_LOCALFILE`, `finishShuffle` will not be called, and buffer in server side may not flush in time, and than reader will fail because read index file fail. as follows `Error happened when get shuffle index for appId[application_xxx], shuffleId[3], partitionId[1], Can't find folder /HDATA/2/rssdata/application_xxx/3/1-1`
   
   @xianjingfeng With current implementation, write shuffle data to N shuffle server can handle the situation about shuffle server failed. But it will cost N times storage.  User can make such choice.
