Arpit Agarwal updated HDFS-4988: -------------------------------- Assignee: Arpit Agarwal > Datanode must support all the volumes as individual storages > ------------------------------------------------------------ > > Key: HDFS-4988 > URL: https://issues.apache.org/jira/browse/HDFS-4988 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Suresh Srinivas > Assignee: Arpit Agarwal > > Currently all the volumes on datanode is reported as a single storage. This > change proposes reporting them as individual storage. This requires: > # A unique storage ID for each storage > #* This needs to be generated during formatting > # There should be an option to allow existing disks to be reported as single > storage unit for backward compatibility. > # A functionality is also needed to split the existing all volumes as single > storage unit to to individual storage units. > # Configuration must allow for each storage unit a storage type attribute. > # Block reports must be sent on a per storage basis. In some cases (such > memory tier) block reports may need to be sent more frequently. That means > block reporting period must be on a per storage type basis. > My proposal is for new clusters to configure volumes by default as separate > storage unit.
