Colin Patrick McCabe updated HDFS-7054:
---------------------------------------
Attachment: HDFS-7054.003.patch
This adds a unit test, and also fixes a bug. the bug was that we were sorting
the whole array and then looking at the first n_used elements. But if the used
elements were greater than 0, the first few elements would be zeroes. This is
fixed by sorting only the first n_used elements rather than the entire array.
Also fixed the hsync double trace thing.
> Make DFSOutputStream tracing more fine-grained
