getEstimatedRegionServerCount

public int getEstimatedRegionServerCount()

Description copied from interface: AdminMask

Estimate the number of regionservers in the HBase cluster. This is usually implemented by calling Admin.getClusterStatus() and then ClusterStatus.getServers() and finally size() on the returned server list.

Specified by:

getEstimatedRegionServerCount in interface AdminMask

Returns:

the number of servers in the cluster or -1 if it could not be determined
