Suresh Srinivas updated HDFS-1936:
----------------------------------
Attachment: HDFS-1936.6.patch
I was not sure how you generated the image tar ball. Will resurrect the check.
> Looks like some spurious changes to DataNode.java
I saw null pointer exceptions in that part of the code. Hence the check during
upgrade tests.
> Indentation slightly off in loadLocalNameINodes
loadLocalNameINodes method is off in indentation (3 spaces instead of two). Any
way I have aligned the new line to the existing code.
> Updating the layout version from HDFS-1822 causes upgrade problems.
