> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Reporter: Wei-Chiu Chuang
> Assignee: Gabor Bota

> When client opens a file, it asks DataNode to check the blocks' visible
> length. If somehow the block is not on the DN, it throws "Cannot append to a
> non-existent replica" message, which is incorrect, because
> getReplicaVisibleLength() is called for different use, just not for appending
> to a block. It should just state "block is not found"
> The following stacktrace comes from a CDH5.13, but it looks like the same
> warning exists in Apache Hadoop trunk.
