Andrew Wong updated KUDU-2286: ------------------------------ Labels: (was: 1.8) > Redistribute tablet data when removing directories > -------------------------------------------------- > > Key: KUDU-2286 > URL: https://issues.apache.org/jira/browse/KUDU-2286 > Project: Kudu > Issue Type: Improvement > Components: fs, tablet > Reporter: Andrew Wong > Priority: Major > > Today, the `update_dirs` tool will allow the removal of a directory, even if > tablet data exists on it. For tablet servers, this means upon the next > startup, those tablets will be re-replicated to other servers. For masters, > this means the node will crash. > While a well-provisioned Kudu cluster should be able to handle both of these > cases, it would be nice to redistribute the tablet's data locally to avoid > either outcome. This entails moving the data blocks from the removed > directory, and rewriting the tablet metadata (which keeps a record of the > data directories across which the tablet's data is stored) to exclude the > removed directory. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
