Subject [jira] [Commented] (HDFS-11122) TestDFSAdmin.testReportCommand fails due to timed out
Date Thu, 10 Nov 2016 19:03:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15654836#comment-15654836

Mingliang Liu commented on HDFS-11122:
--------------------------------------

Triggering block report should help here obviously.

+1

{code}
540	      } catch (IOException ie) {
541	        assertTrue(ie instanceof ChecksumException);
542	      }
{code}
I'd prefer catch the ChecksumException directly and name it ignored. This is minor coding
style preference difference though.

The waitFor is now using 3000 interval, which is too long? 3000 (3 seconds) seems unnecessary
if we can return fast. How about 500/1000?

> After HDFS-11083, the test {{TestDFSAdmi}} fails sometimes dueto timed out. The stack
infos(https://builds.apache.org/job/PreCommit-HDFS-Build/17484/testReport/):
> {code}
> java.lang.Exception: test timed out after 30000 milliseconds
> 	at java.lang.Thread.sleep(Native Method)
> 	at org.apache.hadoop.test.GenericTestUtils.waitFor(GenericTestUtils.java:268)
> 	at org.apache.hadoop.hdfs.tools.TestDFSAdmin.testReportCommand(TestDFSAdmin.java:540)
> {code}
> The timed out is happened in {{GenericTestUtils.waitFor}}. We can make a improvement
in the logic of waiting the corrupt blocks.
