stack commented on HDFS-927:
----------------------------

I also ran full hdfs test suite.  All tests passed though it failed in 
test-cactus:

> I think this is a regression caused by HDFS-127 -- DFSInputStream is supposed 
> to only go back to the NN max.block.acquires times, but in trunk it goes back 
> twice as many - the default is 3, but I am counting 7 calls to 
> getBlockLocations before an exception is thrown.
