Jonathan Hsieh commented on HBASE-5599: --------------------------------------- @ram @fulin I'm working on getting HBASE-5128 into trunk/0.94/0.92/0.90. I'm focusing on trunk first (0.94/0.92 should fall out) and changes from the trunk versions (max merge and specific table safegurds) should make it into the 0.90 version. I believe NOT_IN_META_OR_DEPLOYED, NOT_IN_META, HOLE_IN_REGION_CHAIN are handled by the HBASE-5128. I believe the others are shortcomings. Fulin, give me a few days to get HBASE-5128 in -- I'm testing a prerequisite of it currently (HBASE-5589). > The hbkc tool can not fix the six scenarios, it is NO_VERSION_FILE, > NOT_IN_META_OR_DEPLOYED, NOT_IN_META, SHOULD_NOT_BE_DEPLOYED, > FIRST_REGION_STARTKEY_NOT_EMPTY, HOLE_IN_REGION_CHAIN. > ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: HBASE-5599 > URL: https://issues.apache.org/jira/browse/HBASE-5599 > Project: HBase > Issue Type: New Feature > Components: hbck > Affects Versions: 0.90.6 > Reporter: fulin wang > Fix For: 0.90.6 > > Attachments: hbase-5599-0.90.patch > > > The hbck tool can not fix the six scenarios. > 1. Version file does not exist in root dir. > Fix: I try to create a version file by 'FSUtils.setVersion' method. > > 2.
