---------------------------------------
Summary: MOB snapshot is broken when FileBased SFT is used
Key: HBASE-27017
URL: https://issues.apache.org/jira/browse/HBASE-27017
Project: HBase
Issue Type: Bug
Components: mob
Affects Versions: 3.0.0-alpha-2, 2.5.0
Reporter: Szabolcs Bukros
During snapshot MOB regions are treated like any other region. When a snapshot
is taken and hfile references are collected a StoreFileTracker is created to
get the current active hfile list. But the MOB region stores are not tracked so
an empty list is returned, resulting in a broken snapshot. When this snapshot
is cloned the resulting table will have no MOB files or references.
The problematic code can be found here:
