------------------------------------------
Summary: Meta region edits not recovered while migrating to 0.96.0
Key: HBASE-9110
URL: https://issues.apache.org/jira/browse/HBASE-9110
Project: HBase
Issue Type: Bug
Components: migration
Affects Versions: 0.94.10, 0.95.2
Reporter: Himanshu Vashishtha
I was doing the the migration testing from 0.94.11-snapshot to 0.95.0, and
faced this issue.
1) Do some edits in meta table (for eg, create a table).
2) Kill the cluster.
(I used kill because we would be doing log splitting when upgrading anyway).
3) There is some dependency on WALs. Upgrade the bits to 0.95.2-snapshot. Start
the cluster.
Every thing comes up. I see log splitting happening as expected. But, the
WAL-data for meta table is missing.
I could see recovered.edits file for meta created, and placed at the right
location. It is just that the new HMaster code tries to recover meta by looking
at meta prefix in the log name, and if it didn't find one, just opens the meta
region. So, the recovered.edits file, created afterwards, is not honored.
Opening this jira to let folks give their opinions about how to tackle this
migration issue.
