Tsz Wo Nicholas Sze commented on HDFS-13314:
--------------------------------------------
[~arpitagarwal], thanks for the update. I have one minor comment and a
question:
- In saveNamespace, savedImage is always true in the if-statement at the end.
So that we can remove it.
- Question: why using ExitUtil.terminate(-1) but not thrown an IOException?
> NameNode should optionally exit if it detects FsImage corruption

> The NameNode should optionally exit after writing an FsImage if it detects
> the following kinds of corruptions:
> # INodeReference pointing to non-existent INode
> # Duplicate entries in snapshot deleted diff list.
> This behavior is controlled via an undocumented configuration setting, and
> disabled by default.
