> ABFS: Fixing Test Script Bug and Some Known test Failures in ABFS Test Suite
> ----------------------------------------------------------------------------
>
> Key: HADOOP-19129
> URL: https://issues.apache.org/jira/browse/HADOOP-19129
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.4.0, 3.4.1
> Reporter: Anuj Modi
> Assignee: Anuj Modi
> Priority: Major
> Labels: pull-request-available

> Test Script used by ABFS to validate changes has following two issues:
> # When there are a lot of test failures or when error message of any failing
> test becomes very large, the regex used today to filter test results does not
> work as expected and fails to report all the failing tests.
> To resolve this, we have come up with new regex that will only target one
> line test names for reporting them into aggregated test results.
> # While running the test suite for different combinations of Auth type and
> account type, we add the combination specific configs first and then include
> the account specific configs in core-site.xml file. This will override the
> combination specific configs like auth type if the same config is present in
> account specific config file. To avoid this, we will first include the
> account specific configs and then add the combination specific configs.
> Due to above bug in test script, some test failures in ABFS were not getting
> our attention. This PR also targets to resolve them. Following are the tests
> fixed:
> Following tests are failing on OSS trunk:
> # ITestAbfsClient.testListPathWithValueGreaterThanServerMaximum(): Fails
> Intermittently only for HNS enabled accounts. Test wants to assert that
> client.list() does not return more objects than what is configured in
> maxListResults. Assertions should be that number of objects returned should
> be less than expected as server might end up returning even lesser due to
> partition splits along with a continuation token.
> # ITestGetNameSpaceEnabled.testGetIsNamespaceEnabledWhenConfigIsTrue(): Fail
> when "fs.azure.test.namespace.enabled" config is missing. Ignore the test if
> config is missing.
> # ITestGetNameSpaceEnabled.testGetIsNamespaceEnabledWhenConfigIsFalse():
> Fail when "fs.azure.test.namespace.enabled" config is missing. Ignore the
> test if config is missing.
> # ITestGetNameSpaceEnabled.testNonXNSAccount(): Fail when
> "fs.azure.test.namespace.enabled" config is missing. Ignore the test if
> config is missing.
> # ITestAbfsStreamStatistics.testAbfsStreamOps: Fails when
> "fs.azure.test.appendblob.enabled" is set to true. Test wanted to assert that
> number of read operations can be more in case of append blobs as compared to
> normal blob becuase of automatic flush. It could be same as that of normal
> blob as well.
> # ITestAzureBlobFileSystemCheckAccess.testCheckAccessForAccountWithoutNS:
> Fails for FNS Account only when following config is present:
> fs.azure.account.hns.enabled". Failure is because test wants to assert that
> when driver does not know if the account is HNS enabled or not it makes a
> server call and fails. But above config is letting driver know the account
> type and skipping the head call. Remove these configs from the test specific
> configurations and not from the account settings file.
> # ITestAbfsTerasort.test_120_terasort: Fails with OAuth on HNS account.
> Failure is because of identity mismatch. OAuth uses service principle OID as
> owner of the resources whereas Shared Key uses local system identities. Fix
> is to set configs that will allow overwrite of OID to localidentity. This
> will require a new config to be set by user that specify which OID has to be
> substituted. OAuth by default uses Superuser Identity, so same needs to be
> configured to be overwritten as well.
> *New test config:
> "fs.azure.account.oauth2.client.service.principal.object.id"*
> # ITestExponentialRetryPolicy.testThrottlingIntercept: Fails with SharedKey
> only. Test was using a dummy account to create a new instance of
> AbfsConfiguration and for that dummy account, SharedKey was not configured.
> Fix is to Add non-account specific SharedKey in accountconfigs.
> # ITestAzureBlobFileSystemAuthorization: Fails when contract related configs
> are not present with NPE. Fix is to Ignore if required configs are not
> present.
> # ITestAzureBlobFileSystemAppend.testCloseOfDataBlockOnAppendComplete():
> Fails when append blob is enabled. Append Blobs does not require explicit
> flush and hence flush/close related asserts do not work for append blobs.
> # ITestAzureBlobFileSystemLease:testTwoCreate(): Fail when
> "fs.azure.test.namespace.enabled" config is missing. Fix is to Ignore the
> test if config is missing.
> # ITestAzureBlobFileSystemChecksum.testAppendWithChecksumAtDifferentOffsets:
> Fail when "fs.azure.test.appendblob.enabled" config is true. Fix is to Ignore
> the test if config is true.
