> We are tried the EC function on 80 node cluster with hadoop 3.1.1, we hit the
> same scenario as you said https://issues.apache.org/jira/browse/HDFS-8881.
> Following are our testing steps, hope it can helpful.(following DNs have the
> testing internal blocks)
> # we customized a new 10-2-1024k policy and use it on a path, now we have 12
> internal block(12 live block)
> # decommission one DN, after the decommission complete. now we have 13
> internal block(12 live block and 1 decommission block)
> # then shutdown one DN which did not have the same block id as 1
> decommission block, now we have 12 internal block(11 live block and 1
> decommission block)
> # after wait for about 600s (before the heart beat come) commission the
> decommissioned DN again, now we have 12 internal block(11 live block and 1
> duplicate block)
> # Then the EC is not reconstruct the missed block
> We think this is a critical issue for using the EC function in a production
> env. Could you help? Thanks a lot!
