Tsuyoshi Ozawa commented on MAPREDUCE-6165:
-------------------------------------------
[~ajisakaa] Thank you for taking this issue.
Why not using assertEquals(2, splits.size())?
{code}
- assertEquals(2, splits.size());
+ assertTrue(splits.size() >= 1);
+ assertTrue(splits.size() <= 2);
{code}
I think some applications depend on the ordering...maybe it would be good to
use TreeMap<K,V> or LinkedHashMap<K, V> instead of HashMap.
