[jira] [Updated] (HIVE-14165) Enable faster S3 Split Computation by listing files in blocks

["Abdullah Yousufi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-14165?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Abdullah Yousufi updated HIVE-14165:
------------------------------------
    Description: 
During split computation when a large number of files are required to be listed from S3, instead of executing 1 API call per file, one can optimize by listing 1000 files in each API call. This would reduce the amount of time required for listing files.

Qubole has this optimization in place as detailed here: https://www.qubole.com/blog/product/optimizing-hadoop-for-s3-part-1/?nabe=5695374637924352:0
