* Replicate write failures Currently, when a primary write operation fails after generating a sequence number, the failure is not communicated to the replicas. Ideally, every operation which generates a sequence number on primary should be recorded in all replicas. In this change, a sequence number is associated with write operation failure. When a failure with an assinged seqence number arrives at a replica, the failure cause and sequence number is recorded in the translog and the sequence number is marked as completed via executing `Engine.noOp` on the replica engine. * use zlong to serialize seq_no * Incorporate feedback * track write failures in translog as a noop in primary * Add tests for replicating write failures. Test that document failure (w/ seq no generated) are recorded as no-op in the translog for primary and replica shards * Update to master * update shouldExecuteOnReplica comment * rename indexshard noop to markSeqNoAsNoOp * remove redundant conditional * Consolidate possible replica action for bulk item request depanding on it's primary execution * remove bulk shard result abstraction * fix failure handling logic for bwc * add more tests * minor fix * cleanup * incorporate feedback * incorporate feedback * add assert to remove handling noop primary response when 5.0 nodes are not supported |
