> Provide option to not capture the accessTime change of a file to snapshot if

> Key: HDFS-12191
> URL: https://issues.apache.org/jira/browse/HDFS-12191
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs, namenode
> Affects Versions: 3.0.0-beta1
> Reporter: Yongjun Zhang
> Assignee: Yongjun Zhang
> Attachments: HDFS-12191.001.patch, HDFS-12191.002.patch

>
> Currently, if the accessTime of a file changed before a snapshot is taken,
> this accessTime will be captured in the snapshot, even if there is no other
> modifications made to this file.
> Because of this, when we calculate snapshotDiff, more work need to be done
> for this file, e,g,, metadataEquals method will be called, even if there is
> no modification is made (thus not recorded to snapshotDiff). This can cause
> snapshotDiff to slow down quite a lot when there are a lot of files to be
> examined.
> This jira is to provide an option to skip capturing accessTime only change to
> snapshot. Thus snapshotDiff can be done faster.
> When accessTime of a file changed, if there is other modification to the
> file, the access time will still be captured in snapshot.
> Sometimes we want accessTime be captured to snapshot, such that when
> restoring from the snapshot, we know the accessTime of this snapshot. So this
> new feature is optional, and is controlled by a config property.
> Worth to mention is, how accurately the acessTime is captured is dependent on
> the following config that has default value of 1 hour, which means new access
> within an hour of previous access will not be captured.
