[jira] [Commented] (HADOOP-14266) S3Guard:
S3AFileSystem::listFiles() to employ MetadataStore
[ https://issues.apache.org/jira/browse/HADOOP-14266?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15953827#comment-15953827 ]
Steve Loughran commented on HADOOP-14266:
-----------------------------------------
This may be fastest first just to revert to an incremental tree walk. What I Don't want to have happen is people being told not to use this call, because it delivers such a great speedup for raw S3; you can't even attempt a {{listFiles("s3a:://landsat-pds/", true)}} in Hadoop 2.7 without the code appearing to hang, there are too many objects in that bucket for it to handle.
