Subject [jira] [Created] (HIVE-14323) Reduce number of FS permissions and redundant FS operations
Date Mon, 25 Jul 2016 05:40:20 GMT
Rajesh Balamohan created HIVE-14323:
---------------------------------------

             Summary: Reduce number of FS permissions and redundant FS operations
                 Key: HIVE-14323
                 URL: https://issues.apache.org/jira/browse/HIVE-14323
             Project: Hive
          Issue Type: Improvement
            Reporter: Rajesh Balamohan
            Priority: Minor



Some examples are given below.
1. When creating stage directory, FileUtils sets the directory permissions by running a set
of chgrp and chmod commands. In systems like S3, this would not be relevant.
2. In some cases, fs.delete() is followed by fs.exists(). In this case, it might be redundant
to check for exists() (lookup ops are expensive in systems like S3).
