hbck error after upgrade from 0.94.6 to 0.95.1
Hi,
after I upgrade hbase from 0.94.6 to 0.95.1 on a test machine, the hbck
output complains there is one inconsistency, but the check status is OK
on the former hbase 0.94.6 cluster.
The check output is as follows:
Version: 0.95.1-hadoop2
.
Number of empty REGIONINFO_QUALIFIER rows in .META.: 0
Number of Tables: 1896
Number of live region servers: 1
Number of dead region servers: 0
Master: TEST1,60000,1371762761508
Number of backup masters: 0
ERROR: Region { meta => null, hdfs =>
hdfs://TEST1:19000/hbase-web-test/-ROOT-/70236052, deployed => } on
HDFS, but not listed in META or deployed on any region server
Summary:
.META. is okay.
Number of regions: 1
Deployed on: TEST1,61020,1371762761998
.......omitted content..........
1 inconsistencies detected.
Status: INCONSISTENT
What might be the problem?

Hi,
After I renamed -ROOT- to -ROOT-RENAMED-, and started hbase 0.95.1 again,
it created a new -ROOT- directory.

Best Wishes

-ROOT- has been removed in 0.95 release.
hbck should be able to give better diagnostic message in this regard.
