---------------------------------
Summary: ExportSnapshot support specify storage policy
Key: HBASE-29238
URL: https://issues.apache.org/jira/browse/HBASE-29238
Project: HBase
Issue Type: Improvement
Reporter: Reid Chan
If storage policy is unspecified, the default is either HOT or DISK.
In our production case, we have a cluster which support DISK in `a` IDC while
SSD only in `b` IDC (yes, it is cross-IDC cluster).
We want to export a snapshot to `b` IDC using all SSD directly, but since
default policy, it will be `DISK`. We have to trigger a `major compaction` to
move all data from `DISK` to `SSD` which it is time consuming.
That's the background of this improvement.
