> Compaction and Versions
> When you create a Column Family, you can specify the maximum number of
> versions to keep, by specifying HColumnDescriptor.setMaxVersions(int
> versions). The default value is 3. If more versions than the specified
> maximum exist, the excess versions are filtered out and not written back to
> the compacted StoreFile.
> {quote}
> This is incorrect, the default value is 1.
> Additionally, HColumnDescriptor is deprecated and the example should use
> ColumnFamilyDescriptorBuilder$setMaxVersions(int) instead.
