---------------------------------
Summary: Persist the store engine configuration to TableDescriptor
when creating table
Key: HBASE-26246
URL: https://issues.apache.org/jira/browse/HBASE-26246
Project: HBase
Issue Type: Sub-task
Components: HFile
Reporter: Duo Zhang
As discussed in this section in the design doc:
https://docs.google.com/document/d/16Nr1Fn3VaXuz1g1FTiME-bnGR3qVK5B-raXshOkDLcY/edit#heading=h.78r2mdeyquug
If we use different SFT implementation at master side and region server side,
it is likely to cause data loss, which is a very serious misconfiguration
problem.
A possible solution is to make sure that master and region server always load
the configurations about StoreEngine from the same place. To archive this, a
possible way is to always set the StoreEngine configurations to the
TableDescriptor, even if user does not explicitly set it when creating a table.
And also, when upgrading, we should check whether the existing tables have
StoreEngine configurations, if not, we need to set them.
