Chris Douglas commented on HADOOP-3790:
---------------------------------------
The patch looks good. A few suggestions:
* Instead of local blocks, each of these should probably be separate tests. All
can use the same static MiniDFSCluster using TestSetup, as in TestDatamerge,
TestReduceFetch, etc.
* In TC11, does it make sense to check the return value of fs.rename?
* Since it's essentially dead code in trunk, it might make more sense to make
TC3 part of HADOOP-4379 instead of enabling it once it can be expected to pass
> Add more unit tests to test appending to files in HDFS
