The main changes include: a) Adding a {{LocatedBlockBuilder}} that is used to build {{LocatedBlocks}}. b) Adding a {{ProvidedBlocksBuilder}} as a subclass of {{LocatedBlockBuilder}}, which is used to build {{LocatedBlocks}} for provided blocks -- the {{ProvidedBlocksBuilder}} assigns a randomly chosen Datanode (which reports as provided volume) as the location of the provided blocks. c) Adding a {{ProvidedStorageMap}} which is used to keep track of datanodes with provided volumes d) Modifications to the {{BlockManager}} to use {{LocatedBlockBuilder}} to build {{LocatedBlocks}} and use {{ProvidedStorageMap}} while processing reports from datanodes. > Namenode support for data stored in external stores. > ---------------------------------------------------- > > Key: HDFS-11190 > URL: https://issues.apache.org/jira/browse/HDFS-11190 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Virajith Jalaparti > Attachments: HDFS-11190-HDFS-9806.001.patch > > > The goal of this JIRA is to enable the Namenode to know about blocks that are in {{PROVIDED}} stores and are not necessarily stored on any Datanodes. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
