[ http://issues.apache.org/jira/browse/HADOOP-619?page=comments#action_12455541 ] eric baldeschwieler commented on HADOOP-619: --------------------------------------------
owen: yes arkady: -input ...somepath/*/*.gz or somesuch should work in this proposal, so that should solve your problem, right? Maybe I should relax on allowing directories in glob patterns and directories. It is just that this sort of matching can be really messy on typos. Standard unix tools don't allow it. But I guess as long as it is not recursive, the limits of input formats and such should keep this from going too nuts. So I'm ok with owen's proposal. (No recursion, right?) > Unify Map-Reduce and Streaming to take the same globbed input specification > --------------------------------------------------------------------------- > > Key: HADOOP-619 > URL: http://issues.apache.org/jira/browse/HADOOP-619 > Project: Hadoop > Issue Type: Improvement > Components: mapred > Reporter: eric baldeschwieler > Assigned To: Sanjay Dahiya > > Right now streaming input is specified very differently from other map-reduce > input. It would be good if these two apps could take much more similar input > specs. > In particular -input in streaming expects a file or glob pattern while MR > takes a directory. It would be cool if both could take a glob patern of > files and if both took a directory by default (with some patern excluded to > allow logs, metadata and other framework output to be safely stored). > We want to be sure that MR input is backward compatible over this change. I > propose that a single file should be accepted as an input or a single > directory. Globs should only match directories if the paterns is '/' > terminated, to avoid massive inputs specified by mistake. > Thoughts? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
