Chris Nauroth commented on HADOOP-12551: ---------------------------------------- [~dchickabasapa], thank you for the patch. This looks good overall. Just 2 comments: # I think there are going to be some warnings on code style, such as lines that are not less than 80 characters. Clicking Submit Patch for a pre-commit run would reveal the specifics. # The multi-threaded tests do this: {code} // Setting the value to 1000. This is to ensure that // delete thread would get a chance to run at some point // and would be able to delete the test file. int maxCount = 1000; int runCount = 1; while (runCount < maxCount) { inputStream = fs.open(testPath); inputStream.close(); } } {code} Potentially a more reliable way to do this is: {code} while (t.isAlive()) { inputStream = fs.open(testPath); inputStream.close(); } inputStream = fs.open(testPath); inputStream.close(); {code} ...where {{t}} refers to the {{DeleteThread}} instance. This would keep trying until the thread runs to completion. The extra {{open}} outside the loop is for the edge case that the loop body doesn't get a chance to execute after the thread completes the delete. The extra {{open}} would throw the {{FileNotFoundException}} in that case. > Introduce FileNotFoundException for WASB FileSystem API > ------------------------------------------------------- > > Key: HADOOP-12551 > URL: https://issues.apache.org/jira/browse/HADOOP-12551 > Project: Hadoop Common > Issue Type: Bug > Components: tools > Affects Versions: 2.7.1 > Reporter: Dushyanth > Assignee: Dushyanth > Attachments: HADOOP-12551.001.patch > > > HADOOP-12533 introduced FileNotFoundException to the read and seek API for > WASB. The open and getFileStatus api currently throws FileNotFoundException > correctly when the file does not exists when the API is called but does not > throw the same exception if there is another thread/process deletes the file > during its execution. This Jira fixes that behavior. > This jira also re-examines other Azure storage store calls to check for > BlobNotFoundException in setPermission(), setOwner, rename(), delete(), > open(), listStatus() APIs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
