Feilong He commented on HDFS-14805: ----------------------------------- To push this feature further, we filed another Jira (HDFS-15714) with this Jira incorporated. We developed the feature based the pending patches in the community, from [~virajith], [~ehiggs], etc. The basic design keeps almost unchanged. Thanks these folks for their great contribution. > Mounting external stores in HDFS on-the-fly > ------------------------------------------- > > Key: HDFS-14805 > URL: https://issues.apache.org/jira/browse/HDFS-14805 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Virajith Jalaparti > Priority: Major > Attachments: dynamic-mounts-in-hdfs.pdf > > > Provided storage (HDFS-9806) allows HDFS to address data in external storage > systems, including cloud stores. Data mounted in this manner, seamlessly, > appears to be part of HDFS for applications/clients. The external data can > also be cached by HDFS on local disks and SSDs, accelerating remote data > reads (HDFS-13069). > However, Provided storage was originally targeted at ephemeral HDFS > deployments in the cloud (e.g., Azure HDInsight). Long running HDFS clusters > are common in many other scenarios which can benefit from accessing data in > remote stores. This JIRA targets such scenarios and aims to provide the > ability to: > (a) Dynamically mount external stores in a HDFS cluster while supporting high > availability. > (b) Mount multiple remote stores simultaneously. > (c) Reduce deployment overheads and simplify usability of Provided storage. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
