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). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
