Lei Yang updated HDFS-16828:
----------------------------
Description:
Fsck use corrputedFIles.size instead of blockManager.getMissinngBlockCount() to
get missing blocks. This creates inconsistency with metasave.
In the case where orphaned block is present, metasave and fsck show different
result:
metasave shows:
{code:java}
Metasave: Blocks currently missing: 1
[orphaned]: blk_106452613228_105447711565 MISSING (replicas: l: 0 d: 0 c: 0 e:
0){code}
but fsck -list-corruptfileblocks shows different count:
{noformat}
The filesystem under path '/' has 0 CORRUPT files
{noformat}
This also created inconsistency between dfshealth ui. In dfshealth UI:
* Missing blocks count comes from blockManager.getMissinngBlockCount()
* Corrupted file comes from fsck: NamenodeFsck.listCorruptFileBlocks() which
doesn't count orphaned blocks.
