Question

这个例外是在HBase中提出的，当时有大量的写作簇：

 WARN org.apache.hadoop.ipc.HBaseServer: IPC Server listener on 60020: readAndProcess threw exception java.io.IOException: Connection reset by peer. Count of bytes read: 0

提出这个警告：

Answer 1

这是由于写不重写但写得很大。 "processingtimems":761893表示写操作未在761秒内完成。在操作完成之前，客户端超时。尝试减少多操作项目计数。

Hbase重写异常
