Mingliang Liu updated HADOOP-14461:
-----------------------------------
Attachment: HADOOP-14461.002.patch
While the account access key is missing,
{code:title=before}
$ hadoop fs -ls wasb://[email protected]/
ls: org.apache.hadoop.fs.azure.AzureException: Container test in account
liuml07.blob.core.windows.net not found, and we can't create it using
anoynomous credentials, and no credentials found for them in the configuration.
{code}
{code:title=after}
$ hadoop fs -ls wasb://[email protected]/
ls: org.apache.hadoop.fs.azure.AzureException: No credentials found for account
liuml07.blob.core.windows.net in the configuration, and we are unable to access
container test in this account using anonymous credentials. Please check if the
container exists first. If it is not publicly available, you have to provide
account credentials
{code}
The v2 patch has been tested against US WEST region. All tests pass except
{{TestFileSystemOperationExceptionHandling}} and
{{TestFileSystemOperationsExceptionHandlingMultiThreaded}} which are not
related here. They are caused by [HADOOP-14478] and are being tracked in
[HADOOP-14500].
{code:title=after reverting HADOOP-14478}
hadoop/hadoop-tools/hadoop-azure $ mvn test -q
Results :
Tests run: 703, Failures: 0, Errors: 0, Skipped: 119
{code}
Ping [~snayak] and [[email protected]] for review.

> Actually, this error message is not very helpful. I'd admire you if you can
> immediately find the root cause of this failure.
> Currently if the test *account* is missing, we simply skip the test with
> meaningful error message. Here if the *account key* is missing, we should do
> the same thing: skip the test, and tell the user why we skip it.
