> This is an extension of bug HDDS-3214.
> steps taken :
> 1) Mounted noise injection FUSE on all datanodes
> 2) Selected 1 datanode from each open pipeline (factor=3)
> 3) Injected WRITE FAILURE noise with error code - ENOENT on
> "hdds.datanode.dir" path of list of datanodes selected in step 2)
> 4) start PUT key operation of size 32 MB.

> Observation :
> ----------------
> PUT key operation failed.
> As there is a WRITE failure in one of the datanodes in the pipeline, 3 way
> commit should fail.
> But it should proceed with 2-way commit and the operation should have been
> successful.
