Vinod Kumar Vavilapalli updated HDFS-5293: ------------------------------------------ Target Version/s: 2.8.0 (was: 3.0.0, 2.4.0) Moving features/enhancements out of previously closed releases into the next minor release 2.8.0. > Symlink resolution requires unnecessary RPCs > -------------------------------------------- > > Key: HDFS-5293 > URL: https://issues.apache.org/jira/browse/HDFS-5293 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode > Affects Versions: 2.0.0-alpha, 3.0.0 > Reporter: Daryn Sharp > Priority: Critical > > When the NN encounters a symlink, it throws an {{UnresolvedLinkException}}. > This exception contains only the path that is a symlink. The client issues > another RPC to obtain the link target, followed by another RPC with the link > target + remainder of the original path. > {{UnresolvedLinkException}} should be returning both the link and the target > to avoid a costly and unnecessary intermediate RPC to obtain the link target. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
