-------------------------------------
Summary: Documentation has incorrect default number of versions
Key: HBASE-22299
URL: https://issues.apache.org/jira/browse/HBASE-22299
Project: HBase
Issue Type: Bug
Components: documentation
Reporter: Peter Somogyi
Reference guide has this section under
[compaction|https://hbase.apache.org/book.html#compaction].

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.
