Subject [jira] [Updated] (HADOOP-10942) Globbing optimizations and regression fix
Date Fri, 13 May 2016 20:31:13 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10942?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Colin Patrick McCabe updated HADOOP-10942:
------------------------------------------
    Resolution: Fixed
        Status: Resolved  (was: Patch Available)

The regression fix referred to here was fixed in HADOOP-10957.  The optimizations are already
implemented (we don't perform an RPC on each path component, only when we need to do so to
implement a wildcard.)

> 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.
