Hudson commented on HBASE-4375: ------------------------------- Integrated in HBase-TRUNK #2232 (See [https://builds.apache.org/job/HBase-TRUNK/2232/]) HBASE-4375 [hbck] Add region coverage visualization to hbck stack : Files : * /hbase/trunk/CHANGES.txt * /hbase/trunk/src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java > [hbck] Add region coverage visualization to hbck > ------------------------------------------------ > > Key: HBASE-4375 > URL: https://issues.apache.org/jira/browse/HBASE-4375 > Project: HBase > Issue Type: New Feature > Affects Versions: 0.94.0, 0.90.5 > Reporter: Jonathan Hsieh > Assignee: Jonathan Hsieh > Fix For: 0.90.5 > > Attachments: > 0001-HBASE-4375-Add-region-coverage-visualization-to-hbck.patch > > > After HBASE-4322 and HBASE-4321, we now have an accurate region splits / > coverage map for properly identifying holes, overlaps, backwards regions and > other kinds of problems in the .META. table. hbck should display this > information so that someone can fix this. > A simple version for a table with regions [,A], [A,B], [A,C], [C,] and would > dump out something like this (showing an overlap in [A,B]) > : ['table,,..', 'table,A,..'] > A: ['table,A,..', 'B'] ['table,A,..', 'C'] > B: ['table,A,..', 'C'] > C: ['table,C', ''] > null: > My first thought is '-details' should this dump the full region map including > all good and bad regions. Without -details, any errors should dump info with > some context -- dump one region before problems, problem regions, and then > one post problem region. > Alternately we could add a new option or options to dump the region split map. > What is the preferred way to toggle display of this information in hbck? -- This message is automatically generated by JIRA.
