-------------------------------------
Hey [~hexiaoqiao],
With HDFS-15200 in, this won't pitch in directly, unless we turn the config
introduced there to false, I got this issue before that jira, so in default
configuration this won't happen.
Yes, if we turn off that conf, this can surface, You can take a call on this
whether to hold or not, If there are any review comments, I will try address
them at earliest.

> Key: HDFS-15170

> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Ayush Saxena
> Assignee: Ayush Saxena
> Priority: Critical
> Attachments: HDFS-15170-01.patch, HDFS-15170-02.patch,

> Steps to Repro :
> 1. Start writing a EC file.
> 2. After more than one stripe has been written, stop one datanode.
> 3. Post pipeline recovery, keep on writing the data.
> 4.Close the file.
> 5. transition the namenode to standby and back to active.
> 6. Turn on the shutdown datanode in step 2
> The BR from datanode 2 will make the block corrupt and during invalidate
> block won't remove it, since post failover the blocks would be on stale
> storage.
