Geoffrey Yu commented on CASSANDRA-9876: ---------------------------------------- It looks like the new check for ensuring both {{--dc}} and {{--hosts}} are not specified together is causing the {{RepairOptionTest.testParseOptions}} test to fail. I'll take a look at fixing it and I'll add some new ones for the pull repair option parsing. > One way targeted repair > ----------------------- > > Key: CASSANDRA-9876 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9876 > Project: Cassandra > Issue Type: Improvement > Reporter: sankalp kohli > Assignee: Geoffrey Yu > Priority: Minor > Fix For: 3.x > > Attachments: 9876-dtest-master.txt, 9876-trunk-v2.txt, 9876-trunk.txt > > > Many applications use C* by writing to one local DC. The other DC is used > when the local DC is unavailable. When the local DC becomes available, we > want to run a targeted repair b/w one endpoint from each DC to minimize the > data transfer over WAN. In this case, it will be helpful to do a one way > repair in which data will only be streamed from other DC to local DC instead > of streaming the data both ways. This will further minimize the traffic over > WAN. This feature should only be supported if a targeted repair is run > involving 2 hosts. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
