----------------------------------
Summary: Implement retry logic around starting exclusive backup
operation
Key: HBASE-19441

Project: HBase
Issue Type: Improvement
Components: backup&restore
Reporter: Josh Elser
Fix For: 3.0.0

Specifically, the client does a checkAndPut to specifics coordinates in the
backup table and throws an exception when that fails. Remember that backups are
client driven (per some design review from a long time ago), so queuing is
tough to reason about (we have no "centralized" execution system to use). At a
glance, it seems pretty straightforward to add some retry/backoff semantics to
BackupSystemTable#startBackupExclusiveOperation().

While we are in a state in which backup operations cannot be executed in
parallel, it would be nice to provide some retry logic + configuration. This
would alleviate users from having to build this themselves.
