Uma Maheswara Rao G resolved HDFS-15427. ---------------------------------------- Fix Version/s: 3.4.0 Hadoop Flags: Reviewed Resolution: Fixed Thanks a lot [~ayushsaxena] for reviews! > Merged ListStatus with Fallback target filesystem and InternalDirViewFS. > ------------------------------------------------------------------------ > > Key: HDFS-15427 > URL: https://issues.apache.org/jira/browse/HDFS-15427 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: viewfs > Affects Versions: 3.2.1 > Reporter: Uma Maheswara Rao G > Assignee: Uma Maheswara Rao G > Priority: Major > Fix For: 3.4.0 > > > Currently ListStatus will not consider fallback directory when passed path is > an internal Directory(except root). > Since we configured fallback, we should be able to list fallback directories > when passed path is internal directory. It should list the union of > fallbackDir and internalDir. > So, that fallback directories will not be shaded when path matched to > internal dir. > > The idea here is, user configured default filesystem with fallback fs, then > every operation not having link should go to fallback fs. That way users need > not configure all paths as mount from default fs. > > This will be very useful in the case of ViewFSOverloadScheme. > In ViewFSOverloadScheme, if you choose your existing cluster to be configured > as fallback fs, then you can configure desired mount paths to external fs and > rest other path should go to fallback. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
