Liang Xie created HDFS-6627:
-------------------------------
Summary: 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}
