> RBF: Client maybe get an unexpected result with network anomaly
> ----------------------------------------------------------------
>
> Key: HDFS-15079
> URL: https://issues.apache.org/jira/browse/HDFS-15079
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: rbf
> Affects Versions: 3.3.0
> Reporter: Fei Hui
> Priority: Critical
> Attachments: HDFS-15079.001.patch, HDFS-15079.002.patch,
> UnexpectedOverWriteUT.patch
>
>
> I find there is a critical problem on RBF, HDFS-15078 can resolve it on some
> Scenarios, but i have no idea about the overall resolution.
> The problem is that
> Client with RBF(r0, r1) create a file HDFS file via r0, it gets Exception and
> failovers to r1
> r0 has been send create rpc to namenode(1st create)
> Client create a HDFS file via r1(2nd create)
> Client writes the HDFS file and close it finally(3rd close)
> Maybe namenode receiving the rpc in order as follow
> 2nd create
> 3rd close
> 1st create
> And overwrite is true by default, this would make the file had been written
> an empty file. This is an critical problem
> We had encountered this problem. There are many hive and spark jobs running
> on our cluster, sometimes it occurs
