Manoj Govindassamy updated HDFS-9063:
-------------------------------------
Attachment: test.002.patch
[~jingzhao],
Tried querying {{ContentSummary}} for the Directory which has snapshots, and
still I don't see ContentSummary's {{SnpashotDirectoryCount}} reflecting any
snapshots taken. Is there any other way of querying the ContentSummary which
will reflect the right Snap Dir Count ? Please clarify.
Output from attached test v002.
{noformat}
ContentSummary: /foo - Dir: 2, SnapDir: 0, SnapFile: 0
ContentSummary: /foo/bar - Dir: 1, SnapDir: 0, SnapFile: 0
Count /foo - none inf none inf
2 0 0 /foo
Created Snaphot: /foo/.snapshot/s1
Created Snaphot: /foo/.snapshot/s2
Count /foo - none inf none inf
2 0 0 /foo
ContentSummary: /foo - Dir: 2, SnapDir: 0, SnapFile: 0
ContentSummary: /foo/bar - Dir: 1, SnapDir: 0, SnapFile: 0
ContentSummary: /foo/.snapshot/s1 - Dir: 2, SnapDir: 0, SnapFile: 0
ContentSummary: /foo/.snapshot/s2 - Dir: 2, SnapDir: 0, SnapFile: 0

> The current getContentSummary implementation does not take into account the
> snapshot path, thus if we have the following ops:
> 1. create dirs /foo/bar
> 2. take snapshot s1 on /foo
> 3. create a 1 byte file /foo/bar/baz
> then "du /foo" and "du /foo/.snapshot/s1" can report same results for "bar",
> which is incorrect since the 1 byte file is not included in snapshot s1.
> In the meanwhile, the snapshot diff list size is no longer included in the
> computation result. This can bring minor incompatibility but is consistent
> with the change in HDFS-7728.
