ASF GitHub Bot updated HADOOP-18193: ------------------------------------ Labels: pull-request-available (was: ) > Support nested mount points in INodeTree > ---------------------------------------- > > Key: HADOOP-18193 > URL: https://issues.apache.org/jira/browse/HADOOP-18193 > Project: Hadoop Common > Issue Type: Improvement > Components: viewfs > Affects Versions: 2.10.0 > Reporter: Lei Yang > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > Defining following client mount table config is not supported in INodeTree > and will throw FileAlreadyExistsException > fs.viewfs.mounttable.link./foo/bar=hdfs://nn1/foo/bar > fs.viewfs.mounttable.link./foo=hdfs://nn02/foo > > INodeTree has 2 methods that need change to support nested mount points. > createLink(..): build INodeTree during fs init. > resolve(..): resolve path in INodeTree with viewfs apis. > > ViewFileSystem and ViewFs referes INodeTree.resolve(..) to resolve path to > specific mount point. No changes are expected in both classes. However, we > need to support existing use cases and make sure no regression. > > AC: > # INodeTree.createlink should support creating nested mount > points.(INodeTree is constructed during fs init) > # INodeTree.resolve should support resolve path based on nested mount > points. (INodeTree.resolve is used in viewfs apis) > # No regression in existing ViewFileSystem and ViewFs apis. > # Ensure some important apis are not broken with nested mount points. > (Rename, getContentSummary, listStatus...) -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
