Andrew Purtell commented on HBASE-20505:
----------------------------------------
Initial patch. Support the new option for all test types. Specifying multiple
families is not useful for checkAndXXX tests so always only utilize the first
column family for those. For all other tests, assumption is specification of
multiple CFs is a request to raise the work factor accordingly.
> PE should support multi column family read and write cases

> PerformanceEvaluation has a --columns parameter but this adjusts the number
> of distinct column qualifiers to write (and, with --addColumns, to add to the
> scan), not the number of column families.
> We need something like a new --families parameter that will increase the
> number of column families defined in the test table schema, written to, and
> included in gets and scans. Default is 1, current behavior.
