Stephen Chu updated HADOOP-11165:
---------------------------------
Attachment: HADOOP-11165.1.patch
Attaching a fix to {{TestUTF8}}.
{{new String(..., "UTF-8")}} in JDK8 now correctly corresponds to decoding in
_UTF-8_, instead of _Modified UTF-8_ which the {{DataInput}} and {{DataOutput}}
interfaces use.
Made the following changes:
* in _testGetBytes_, we now convert the Modified UTF8 formatted bytes to String
properly using DataInput's {{readUTF}}.
* Remove one test from _testIO_ that uses the {{new String(..., "UTF-8")}} to
decode UTF-8 because that does not read modified UTF8 anymore in JDK8.
I built + ran successfully using JDK6/7/8.
> TestUTF8 fails when run against java 8
