Mukul Kumar Singh updated HDFS-11575: ------------------------------------- Attachment: HDFS-11575.010.patch > Supporting HDFS NFS gateway with Federated HDFS > ----------------------------------------------- > > Key: HDFS-11575 > URL: https://issues.apache.org/jira/browse/HDFS-11575 > Project: Hadoop HDFS > Issue Type: Bug > Components: nfs > Reporter: Mukul Kumar Singh > Assignee: Mukul Kumar Singh > Attachments: HDFS-11575.001.patch, HDFS-11575.002.patch, > HDFS-11575.003.patch, HDFS-11575.004.patch, HDFS-11575.005.patch, > HDFS-11575.006.patch, HDFS-11575.007.patch, HDFS-11575.008.patch, > HDFS-11575.009.patch, HDFS-11575.010.patch, SupportingNFSwithFederatedHDFS.pdf > > > Currently HDFS NFS gateway only supports HDFS as the underlying filesystem. > Federated HDFS with ViewFS helps in improving the scalability of the name > nodes. However NFS is not supported with ViewFS. > With this change, ViewFS using HDFS as the underlying filesystem can be > exported using NFS. ViewFS mount table will be used to determine the exports > which needs to be supported. > Some important points > 1) This patch only supports HDFS as the underlying filesystem for ViewFS. > 2) This patch add support to add more than one export point in the NFS gateway > 3) Root filesystem of the ViewFS will not be mountable for NFS gateway with > ViewFS, > however this will not be the case for NFS gateway with HDFS > 4) A filehandle now apart from the field will also contain an identifier to > identify the name node, this will be used to map to correct name node for > file operations. > Please find the attached pdf document which helps in explaining the design > and the solution. > -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
