Enis Soztutar updated HADOOP-4760:
----------------------------------
Attachment: closehdfsstream_v2.patch
Incorporated Raghu's comments, now checkOpen() is called if closed is false.
Also fixed the DFSClient.close() method to not throw exception.
The @Override's are pretty useful (espcecially when refactoring) and they are
introduced intentionally by my eclipse save actions. I am in favor of keeping
them.
import statements are reordered and * are converted to actual classes again by
save actions. According to our guidelines, the import statements should only
contain actual class references. As in this case here, the import statements
are constantly switched between actual class names or * between patches. Maybe
we should add checking for this to test-patch script.
> HDFS streams should not throw exceptions when closed twice
