----------------------------
Status: Patch Available (was: Open)
> getReplicaVisibleLength() should do checkReadAccess insteading of
> checkWriteAccess
> ----------------------------------------------------------------------------------
>
> Key: HDFS-6627
> URL: https://issues.apache.org/jira/browse/HDFS-6627
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode
> Affects Versions: 3.0.0
> Reporter: Liang Xie
> Assignee: Liang Xie
> Attachments: HDFS-6627.txt
>
>
> Just read getReplicaVisibleLength() code and found it,
> DataNode.checkWriteAccess is only invoked by
> DataNode.getReplicaVisibleLength(), let's rename it to checkReadAccess to
> avoid confusing, since the real impl here is check AccessMode.READ:
> {code}
> blockPoolTokenSecretManager.checkAccess(id, null, block,
> BlockTokenSecretManager.AccessMode.READ);
> {code}
