HalfLegend updated HDFS-12694:
------------------------------
Environment:
There hosted machines and each one have a docker.
Hosted machines: host1, host2, host3
dockers : docker1, docker2, docker3
I installed HDFS in each docker. (version 2.8.1)
Docker1 and Docker2 have name node.
Docker1,2,3 all have data node.
I have a weave network of 10.240.1.0/24
Somebody else installed another HDFS in hosted machine outside docker. （Their
version is 2.7.0）

> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.8.0, 2.7.4, 2.8.1
> Environment: There hosted machines and each one have a docker.
> Hosted machines: host1, host2, host3
> dockers : docker1, docker2, docker3
> I installed HDFS in each docker. (version 2.8.1)
> Docker1 and Docker2 have name node.
> Docker1,2,3 all have data node.

> Somebody else installed another HDFS in hosted machine outside docker. （Their

> Reporter: HalfLegend
>
> Somebody else installed another HDFS in hosted machine outside the dockers.
> But the data node in the hosted machine appears in the docker machine.
> | Node | Http Address | Capacity | Blocks | Block pool used | Version|
> | docker1:50010 (10.240.1.101:50010) | docker1:50075 | 931.06 GB |
> 8420 | 116.64 GB (12.53%) | 2.8.1 |
> | docker2:50010 (10.240.1.102:50010) | docker2:50075 | 916.77 GB | 8420 |
> 116.64 GB (12.72%) | 2.8.1 |
> | docker3:50010 (10.240.1.64:50010) | docker3:50075 | 916.77 GB | 0 | 28 KB
> (0%) | 2.8.1 |
> The IP address of docker3 should be 10..240.1.103, but it is 10.240.1.64 here
> which is the IP address of host3. They also have a data node running on host3.
> We can see in docker3, the used blocks is 0, no data is added here. The
> replication is 3.
> If I use fsck to check the files, many replication blocks are missing. I
> think it is because of the IP address.
> Further more, if I stop the data node in docker3, the heart beat will stop.
> This is correct.
> So it is a weird bug.
