[jira] Commented: (HADOOP-6226) Create a
LimitedByteArrayOutputStream that does not expand its buffer on write
Posted by "Hong Tang (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-6226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12750329#action_12750329 ]
Hong Tang commented on HADOOP-6226:
-----------------------------------
@Jothi, thanks for taking time porting the class to io package and writing unit tests for it. Some comments for consideration:
- The comment of the test case refers to the class LimitedByteArrayOutputStream.
{code}
+/** Unit tests for LimitedByteArrayOutputStream */
{code}
- Should put some random contents in the input byte array. Something like the following (capitalize variable INPUT because it is now static final):
{code}
private static final byte[] INPUT = new byte[SIZE];
static {
new Random().nextBytes(INPUT);
}
{code}
- Suggest to write only one byte to test whether an exception is thrown due to limit exceeded.
- Suggest to test that after reset() and writing INPUT, writing one more byte would cause an exception.
- Suggest to do reset(SIZE-1) instead of reset(SIZE/2).
- Suggest to add an assertion (getLimit() == SIZE) after reset() and (getLimit() == SIZE-1) after reset(SIZE-1).

-----------------------------------
Actually, the same usage exists in TFile too. I wrote a class called BoundedByteArrayOutputStream which is package private. Might it be useful to promote to a public class in io package?

Actually, we will just take care of this inside the Shuffle package itself since the use case seems to be pretty specific
