Subject [jira] [Commented] (HBASE-17603) REST api for scan should return 404 when table does not exist
Date Sat, 11 Feb 2017 12:52:42 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17603?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15862391#comment-15862391

Duo Zhang commented on HBASE-17603:

I think this is the right approach. Then can we just modify the TestScannerResource#testTableDoesNotExist
without changing ClientScanner?

I've marked HBASE-17508 as incompatible change but I think the incompatible thing is acceptable.
Even if we pass the existence check when constructing the scanner, we could still get TableNotFoundException
when calling next.

>          Issue Type: Bug
>          Components: REST, scan
>    Affects Versions: 2.0.0, 1.4.0
>            Reporter: Ted Yu
>            Priority: Blocker
>             Fix For: 2.0.0, 1.4.0
>         Attachments: 17603.v1.txt, 17603.v3.txt, 17603.v4.txt, 17603.v4.txt
> This was the first Jenkins build where TestScannerResource#testTableDoesNotExist started
> https://builds.apache.org/job/HBase-1.4/612/jdk=JDK_1_8,label=Hadoop/testReport/junit/org.apache.hadoop.hbase.rest/TestScannerResource/testTableDoesNotExist/
> The test failure can be reproduced locally.
> The test failure seemed to start after HBASE-17508 went in.
> The problem is introduced after HBASE-17508. After HBASE-17508 we will not contact RS
when getScanner. So for rest, get scanner will not return 404 either. But we should get a
404 when fetching data from the scanner but now it will return 204.
