Subject [jira] [Commented] (YARN-430) Add HDFS based store for RM which manages the store using directories
Date Mon, 01 Jul 2013 00:44:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13696436#comment-13696436

Bikas Saha commented on YARN-430:

We should probably change the FileSystem store to use directories. The original intent of
not using directories was to support key value store targets but all file system impls will/should
have directory support. key value stores mimic directories as table entries.

> There is a generic FileSystem store but it does not take advantage of HDFS features like
directories, replication, DFSClient advanced settings for HA, retries etc. Writing a store
thats optimized for HDFS would be good.
