Subject Re: [VOTE] Release Apache Hadoop 2.8.0 (RC3)
Date Mon, 20 Mar 2017 17:31:33 GMT
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...
