Lars Hofhansl commented on HBASE-18228: --------------------------------------- bq. 2.x will likely rewrite hbck for its particular problems. Hmm... 2.s is a monster as is. I do not think we should do another rewrite of a larger chunk of until 3.x (or whatever the next one is called) > HBCK improvements > ----------------- > > Key: HBASE-18228 > URL: https://issues.apache.org/jira/browse/HBASE-18228 > Project: HBase > Issue Type: Improvement > Components: hbck > Reporter: Lars Hofhansl > Priority: Critical > Fix For: 1.4.0 > > > We just had a prod issue and running HBCK the way we did actually causes more > problems. > In part HBCK did stuff we did not expect, in part we had little visibility > into what HBCK was doing, and in part the logging was confusing. > I'm proposing 2 improvements: > 1. A dry-run mode. Run, and just list what would have been done. > 2. An interactive mode. Run, and for each action request Y/N user input. So > that a user can opt-out of stuff. > [~jmhsieh], FYI -- This message was sent by Atlassian JIRA (v6.4.14#64029)
