------------------------------------
Summary: Globbing optimizations and regression fix
Key: HADOOP-10942
URL: https://issues.apache.org/jira/browse/HADOOP-10942
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 2.1.0-beta, 3.0.0
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Priority: Critical
When globbing was commonized to support both filesystem and filecontext, it
regressed a fix that prevents an intermediate glob that matches a file from
throwing a confusing permissions exception. The hdfs traverse check requires
the exec bit which a file does not have.
Additional optimizations to reduce rpcs actually increases them if directories
contain 1 item.
