> fsck -includeSnapshots reports wrong amount of total blocks
> -----------------------------------------------------------
>
> Key: HDFS-12618
> URL: https://issues.apache.org/jira/browse/HDFS-12618
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: tools
> Affects Versions: 3.0.0-alpha3
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Minor
> Attachments: HDFS-121618.initial, HDFS-12618.001.patch,
> HDFS-12618.002.patch
>
>
> When snapshot is enabled, if a file is deleted but is contained by a
> snapshot, *fsck* will not reported blocks for such file, showing different
> number of *total blocks* than what is exposed in the Web UI.
> This should be fine, as *fsck* provides *-includeSnapshots* option. The
> problem is that *-includeSnapshots* option causes *fsck* to count blocks for
> every occurrence of a file on snapshots, which is wrong because these blocks
> should be counted only once (for instance, if a 100MB file is present on 3
> snapshots, it would still map to one block only in hdfs). This causes fsck to
> report much more blocks than what actually exist in hdfs and is reported in
> the Web UI.
> Here's an example:
> 1) HDFS has two files of 2 blocks each:
> {noformat}
> $ hdfs dfs -ls -R /
> drwxr-xr-x - root supergroup 0 2017-10-07 21:21 /snap-test
> -rw-r--r-- 1 root supergroup 209715200 2017-10-07 20:16 /snap-test/file1
> -rw-r--r-- 1 root supergroup 209715200 2017-10-07 20:17 /snap-test/file2
> drwxr-xr-x - root supergroup 0 2017-05-13 13:03 /test
> {noformat}
> 2) There are two snapshots, with the two files present on each of the
> snapshots:
> {noformat}
> $ hdfs dfs -ls -R /snap-test/.snapshot
> drwxr-xr-x - root supergroup 0 2017-10-07 21:21
> /snap-test/.snapshot/snap1
> -rw-r--r-- 1 root supergroup 209715200 2017-10-07 20:16
> /snap-test/.snapshot/snap1/file1
> -rw-r--r-- 1 root supergroup 209715200 2017-10-07 20:17
> /snap-test/.snapshot/snap1/file2
> drwxr-xr-x - root supergroup 0 2017-10-07 21:21
> /snap-test/.snapshot/snap2
> -rw-r--r-- 1 root supergroup 209715200 2017-10-07 20:16
> /snap-test/.snapshot/snap2/file1
> -rw-r--r-- 1 root supergroup 209715200 2017-10-07 20:17
> /snap-test/.snapshot/snap2/file2
> {noformat}
> 3) *fsck -includeSnapshots* reports 12 blocks in total (4 blocks for the
> normal file path, plus 4 blocks for each snapshot path):
> {noformat}
> $ hdfs fsck / -includeSnapshots
> FSCK started by root (auth:SIMPLE) from /127.0.0.1 for path / at Mon Oct 09
> 15:15:36 BST 2017
> Status: HEALTHY
> Number of data-nodes: 1
> Number of racks: 1
> Total dirs: 6
> Total symlinks: 0
> Replicated Blocks:
> Total size: 1258291200 B
> Total files: 6
> Total blocks (validated): 12 (avg. block size 104857600 B)
> Minimally replicated blocks: 12 (100.0 %)
> Over-replicated blocks: 0 (0.0 %)
> Under-replicated blocks: 0 (0.0 %)
> Mis-replicated blocks: 0 (0.0 %)
> Default replication factor: 1
> Average block replication: 1.0
> Missing blocks: 0
> Corrupt blocks: 0
> Missing replicas: 0 (0.0 %)
> {noformat}
> 4) Web UI shows the correct number (4 blocks only):
> {noformat}
> Security is off.
> Safemode is off.
> 5 files and directories, 4 blocks = 9 total filesystem object(s).
> {noformat}
> I would like to work on this solution, will propose an initial solution
> shortly.
