Wei-Chiu Chuang commented on HDFS-11303:
Hi Chen Zhang. Your 002 patch is mostly good. I updated your latest patch to
address some comments I had. Hope you don't mind.
In addition,
* Added a fail() to ensure DFSInputStream#read() fails as expected.
* Because DFSInputStream#read() throws exception, the asserts are not
reachable. Moved them to catch block.
* Replaced the deprecated method {{IOUtils.cleanup}} with
{{IOUtils.cleanupWithLogger}}.
Regarding my first comment, I verified the test fails without the fix, and
passes with the fix.

Wei-Chiu Chuang commented on HDFS-11303:
Hi [~zhangchen], thanks for filing the jira and posting the patch.
I'd like to help reviewing the patch. The fix itself looks good. Here's my
quick comments, mostly cosmetic:
1. I am not so sure about the test: you mentioned the client had timeouts
connecting to DNs, but the test throws ChecksumException -- it is not clear to
me if client exhibit the same symptom in both scenarios. Perhaps you can use
{{DFSClientFaultInjector.readFromDatanodeDelay}} to insert a delay instead?
2. Could you add test timeout limit? For example a 10 second timeout:
{{\@Test(timeout=10)}}
3. It appears to me that the test expects to throw BlockMissingException.
Instead of the following:
{code}
} catch (BlockMissingException e) {
assertTrue(true);
}
{code} Would you mind update the test and use ExpectedException to assert that
the exception is expected?
4.
{code}
if (true) {
System.out.println("-- throw Checksum Exception");
throw new ChecksumException("ChecksumException test", 100);
}
{code}
Please remove {{if(true)}} and please use DFSClient.LOG instead of
System.out.println for log printing
5. There's a slight code conflict due to HDFS-11708. Please rebase the patch.

He set its state to 'patch available' which triggered a run of the CI system. It looks like one test failed. Do you think it related (let me trigger a rerun... some tests are flakey and fail on occasion irregardless of what the attached patch does). Andrew also flagged this JIRA as affecting 3.0.0-alpha1 which probably make it fit for commit as fix for next hadoop3 release. Let me trigger another run and see how the patch does. I'll leave this issue open another few days in the hope that someone else will chime in with a review. Will commit whether-or-which in a day or two.

[jira] [Commented] (HDFS-11303) Hedged read might hang infinitely if read data from all DN failed
[ https://issues.apache.org/jira/browse/HDFS-11303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15812572#comment-15812572 ] stack commented on HDFS-11303: -- Patch LGTM. Your patch allows that the primary read might still complete before the new hedged reads whereas what was there previous would discard anything that came in after timeout. Good. The test is just to verify we time out? W/o your fix, the test hangs? > Hedged read might hang infinitely if read data from all DN failed > -- > > Key: HDFS-11303 > URL: https://issues.apache.org/jira/browse/HDFS-11303 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs-client >Affects Versions: 3.0.0-alpha1 >Reporter: Chen Zhang > Attachments: HDFS-11303-001.patch > > > Hedged read will read from a DN first, if timeout, then read other DNs > simultaneously. > If read all DN failed, this bug will cause the future-list not empty(the > first timeout request left in list), and hang in the loop infinitely -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
