### Description of PR Refer to HDFS-17365. Currently, when we write ec files. It can tolerate with at most `numAllBlocks - numDataBlocks` failed streamers. However, this can lead to block missing exception in some case. For example, When we use RS-6-3-1024K ec policy, we have written 6 blocks successfully. this block is going to be reconstructed, but before that, one of the 6 blocks lost, we may lose the data forerver. Or if we restart datanode at that time, client will get block missing exception. So, we should better add some redundancy here. -- This is an automated message from the Apache Git Service.
