Akira Ajisaka commented on HDFS-15293:
--------------------------------------
Thank you [~shv] and [~vagarychen]. The change looks straightforward to me.
Minor nits:
* ImageServlet#setRecentImageCheckTimePrecision can be package-private.
* MiniDFSCluster is AutoCloseable, so you can use try-with-resources in the
test.
I'm +1 if these are addressed.
The test failures are not related to the patch. All the tests except
TestBPOfferService passed on my local.

> HDFS-12979 introduced the logic that, if ANN sees consecutive fs image upload
> from Standby with a small delta comparing to previous fsImage. ANN would
> reject this image. This is to avoid overly frequent fsImage in case of when
> there are multiple Standby node. However this check could be too stringent.
