------------------------------------
OK, Thanks for your information, get it. Let's backport to the following branch
once ready.
BTW, The new unit test can pass using [^HDFS-15170-03.patch] without any other
changes in, is it expected?

> 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.
