This would ensure that data backed up from HDFS preserves all the permission information needed when doing a recovery from S3 to HDFS. > Azure WASB does exactly this already. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: common-issues-help@hadoop.apache.org
