By default when using eventual scans and there are no scan servers present then the scan will fall back to tablet servers. This could be very suprising and disruptive when tablet servers do not have much resources allocated for scanning and scan servers do. In the case were scan servers are temporarily down it could cause a thundering herd that overwhelms tablet servers. This commit changes the default behavior to not fall back to tablet servers. This change is targeting 3.1 in order to avoid changing default behavior in 2.1.X. The capability to not fall back to tablet servers was introduced in 2.1.3 via #4671 with a default behavior to fallback. -- This is an automated message from the Apache Git Service.
