Daryn Sharp created HDFS-5293: --------------------------------- Summary: 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 (v6.1#6144)
