--------------------------------------------
Summary: Optionally allow snapshots to preserve cluster's max
filesize config by setting it into table descriptor
Key: HBASE-25548
URL: https://issues.apache.org/jira/browse/HBASE-25548
Project: HBase
Issue Type: Improvement
Reporter: Wellington Chevreuil
Assignee: Wellington Chevreuil
While using snapshots for data migration, if the source cluster has non-default
definition for *hbase.hregion.max.filesize*, table being snapshotted doesn't
have *MAX_FILESIZE* attribute set, then if snapshot is exported to a separate
cluster with different value for *hbase.hregion.max.filesize*, any cloned table
will not respect the original value. In cases where the original cluster had a
much larger value set to *hbase.hregion.max.filesize* then the destination
cluster, restoring snapshot can trigger a storm of splits.
This Jira introduces an optional configuration (disabled by default) that
allows for the *hbase.hregion.max.filesize* value to be saved within the table
*MAX_FILESIZE* descriptor at snapshot creation time.
