Subject [jira] [Updated] (HADOOP-14722) Azure: BlockBlobInputStream position incorrect after seek
Date Wed, 02 Aug 2017 05:35:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-14722?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Thomas Marquardt updated HADOOP-14722:
    Attachment: HADOOP-14722-001.patch

Attaching HADOOP-14722-001.patch.  

The fix includes a new test case (*TestBlockBlobInputStream.test_0201_RandomReadTest*) which
fails without the fix and passes with the fix.

I ran *hadoop-tools/hadoop-azure* tests against my endpoint tmarql3.  All tests are passing
except TestWasbRemoteCallHelper which is tracked by HADOOP-14715 and unrelated to the patch.

Tests run: 765, Failures: 1, Errors: 0, Skipped 70

> The seek, skip, and getPos methods of BlockBlobInputStream do not correctly account for
the stream's  internal buffer.  This results in invalid stream positions.
