licl2014 opened a new issue #10322:
URL: https://github.com/apache/druid/issues/10322


   HttpPostEmitter emit duplicatie failed metrics
   ### Affected Version
   
   0.12.3
   ### Description
   ```
       private void tryEmitOneFailedBuffer()
       {
         FailedBuffer failedBuffer = failedBuffers.peekFirst();
         if (failedBuffer != null) {
           if (sendWithRetries(failedBuffer.buffer, failedBuffer.length, failedBuffer.eventCount, false)) {
             // Remove from the queue of failed buffer.
             failedBuffers.pollFirst();
             approximateFailedBuffersCount.decrementAndGet();
             // Don't add the failed buffer back to the buffersToReuse queue here, because in a situation when we were not
             // able to emit events for a while we don't have a way to discard buffers that were used to accumulate events
             // during that period, if they are added back to buffersToReuse. For instance it may result in having 100
             // buffers in rotation even if we need just 2.
           }
         }
       }
   ```
   `failedBuffer` will be sent many times if  `sendWithRetries` not success.
