Harsha Teja Kanna commented on HUDI-3242:
-----------------------------------------
So what I found from further debugging is that once the --checkpoint 0 is
passed once to Deltastreamer, it will not pick it again if it is same.
[https://github.com/apache/hudi/blob/release-0.10.1/hudi-utilities/src/main/java/org/apache/hudi/utilities/deltastreamer/DeltaSync.java#L471]
I added log statements in a PR to master branch

> Hi, I am testing release branch 0.10.1 as I needed few bug fixes from it.
> However, I see for a certain table. Only partial discovery of files happening
> after the initial commit of the table.
> But if the second partition is given as input for the first commit, all the
> files are getting discovered.
> First partition : 2021/01 has 744 files and all of them are discovered
> Second partition: 2021/02 has 762 files but only 72 are discovered.
> Checkpoint is set to 0.
> No errors in the logs.
