Subject [jira] [Commented] (HADOOP-14259) Verify viewfs works with ADLS
Date Tue, 04 Apr 2017 08:00:51 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14259?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15954758#comment-15954758

John Zhuge commented on HADOOP-14259:

HADOOP-14258 documents client root-mount table implemented inside ADLS connector while viewfs
is more generic.  See the [doc|https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/ViewFs.html].

> -----------------------------
>                 Key: HADOOP-14259
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14259
>             Project: Hadoop Common
>          Issue Type: Test
>          Components: fs/adl, viewfs
>    Affects Versions: 2.8.0
>            Reporter: John Zhuge
>            Priority: Minor
> Many clusters can share a single ADL store as the default filesystem. In order to prevent
directories of the same names but from different clusters to collide, use viewfs over ADLS
> * Set {{fs.defaultFS}} to {{viewfs://clusterX}} for cluster X
> * Set {{fs.defaultFS}} to {{viewfs://clusterY}} for cluster Y
> * The viewfs client mount table should have entry clusterX and ClusterY
> Tasks
> * Verify all filesystem operations work as expected, especially rename and concat
> * Verify homedir entry works
