?Thanks for update, John. Then we should be OK with fixing this issue in 2.8.1.
Mark the target version of HADOOP-14205 to 2.8.1 instead of 2.8.0 and bump up
to blocker in case we could miss this in releasing 2.8.1. :)
Thanks,
Junping

Yes, it only affects ADL. There is a workaround of adding these 2 properties to
core-site.xml:
<property>
<name>fs.adl.impl</name>
<value>org.apache.hadoop.fs.adl.AdlFileSystem</value>
</property>
<property>
<name>fs.AbstractFileSystem.adl.impl</name>
<value>org.apache.hadoop.fs.adl.Adl</value>
</property>
I have the initial patch ready but hitting these live unit test failures:
Failed tests:
TestAdlFileSystemContractLive.runTest:60->FileSystemContractBaseTest.testListStatus:257
expected:<1> but was:<10>
Tests in error:
TestAdlFileContextMainOperationsLive>FileContextMainOperationsBaseTest.testMkdirsFailsForSubdirectoryOfExistingFile:254
» AccessControl
TestAdlFileSystemContractLive.runTest:60->FileSystemContractBaseTest.testMkdirsFailsForSubdirectoryOfExistingFile:190
» AccessControl
Stay tuned...

Thank you for reporting the issue, John! Does this issue only affect ADL (Azure
Data Lake) which is a new feature for 2.8 rather than other existing FS? If so,
I think we can leave the fix to 2.8.1 to fix given this is not a regression and
just a new feature get broken.?
Thanks,
Junping

Discovered https://issues.apache.org/jira/browse/HADOOP-14205 "No FileSystem
for scheme: adl".
The issue were caused by backporting HADOOP-13037 to branch-2 and earlier.
HADOOP-12666 should not be backported, but some changes are needed: property
fs.adl.impl in core-default.xml and hadoop-tools-dist/pom.xml.
I am working on a patch.
