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...
