Subject [jira] Commented: (HADOOP-2528) check permissions for job inputs and outputs
Date Fri, 04 Jan 2008 23:03:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12556107#action_12556107

Raghu Angadi commented on HADOOP-2528:
--------------------------------------

This might be ok as temporary feature. IMHO such extra early checks are not very useful and
extra load on the server. I think its better to make sure in rare cases where the permission
is denied, the clear error info percolates up to right places.

> On job submission, filesystem permissions should be checked to ensure that the input
directory is readable and that the output directory is writable.
