<para>If a cluster with a lot of regions, it is possible if an eager beaver
regionserver checks in soon after master start while all the rest in the
cluster are laggardly, this first server to checkin will be assigned all
regions. If lots of regions, this first server could buckle under the
load. To prevent the above scenario happening up the
<varname>hbase.master.wait.on.regionservers.mintostart</varname> from its
default value of 1. See
