[jira] [Updated] (HDFS-8823) Move replication factor into individual blocks
[ https://issues.apache.org/jira/browse/HDFS-8823?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Haohui Mai updated HDFS-8823: - Issue Type: Sub-task (was: Improvement) Parent: HDFS-8966 Move replication factor into individual blocks -- Key: HDFS-8823 URL: https://issues.apache.org/jira/browse/HDFS-8823 Project: Hadoop HDFS Issue Type: Sub-task Reporter: Haohui Mai Assignee: Haohui Mai Fix For: 2.8.0 Attachments: HDFS-8823.000.patch, HDFS-8823.001.patch, HDFS-8823.002.patch, HDFS-8823.003.patch, HDFS-8823.004.patch, HDFS-8823.005.patch, HDFS-8823.006.patch This jira proposes to record the replication factor in the {{BlockInfo}} class. The changes have two advantages: * Decoupling the namespace and the block management layer. It is a prerequisite step to move block management off the heap or to a separate process. * Increased flexibility on replicating blocks. Currently the replication factors of all blocks have to be the same. The replication factors of these blocks are equal to the highest replication factor across all snapshots. The changes will allow blocks in a file to have different replication factor, potentially saving some space. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
