> Underconstruction blocks can be considered missing
> --------------------------------------------------
>
> Key: HDFS-11755
> URL: https://issues.apache.org/jira/browse/HDFS-11755
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.0.0-alpha2, 2.8.1
> Reporter: Nathan Roberts
> Assignee: Nathan Roberts
> Attachments: HDFS-11755.001.patch, HDFS-11755.002.patch,
> HDFS-11755-branch-2.002.patch, HDFS-11755-branch-2.8.002.patch
>
>
> Following sequence of events can lead to a block underconstruction being
> considered missing.
> - pipeline of 3 DNs, DN1->DN2->DN3
> - DN3 has a failing disk so some updates take a long time
> - Client writes entire block and is waiting for final ack
> - DN1, DN2 and DN3 have all received the block
> - DN1 is waiting for ACK from DN2 who is waiting for ACK from DN3
> - DN3 is having trouble finalizing the block due to the failing drive. It
> does eventually succeed but it is VERY slow at doing so.
> - DN2 times out waiting for DN3 and tears down its pieces of the pipeline, so
> DN1 notices and does the same. Neither DN1 nor DN2 finalized the block.
> - DN3 finally sends an IBR to the NN indicating the block has been received.
> - Drive containing the block on DN3 fails enough that the DN takes it offline
> and notifies NN of failed volume
> - NN removes DN3's replica from the triplets and then declares the block
> missing because there are no other replicas
> Seems like we shouldn't consider uncompleted blocks for replication.
