Ivan Mitic commented on HDFS-4584:
----------------------------------
Hi Arpit, thanks for the patch.
I was thinking whether it's possible to alter the problematic test
{{testNewNamenodeTakesOverWriter}} in a way such that it can still run on
Windows. What do you think about doing the following:
1. cluster1#format(true)#build() - same as now, this will generate local image
file and namespace id
2. cluster1#shutdown() - release file locks
3. FileUtil#copy() -
4. cluster1#format(false)#build()
5. cluster1#FileSystem#mkdirs() - move mkdirs here such that it is saved in the
edits log
6. cluster2#format(false)#build()
This should preserve the intent of the test and still allow it to run on
Windows I think. Let me know if this works. I am fine with the current patch if
not.
