DEFAULT_VERSIONS should be 1
----------------------------
Key: HBASE-3730
URL: https://issues.apache.org/jira/browse/HBASE-3730
Project: HBase
Issue Type: Improvement
Reporter: Joe Pallas
Priority: Minor
The current DEFAULT_VERSIONS (in HColumnDescriptor) is 3, but there is no
particular reason for this. Many uses require only 1, and having a default
that is different makes people confused (e.g., "Do I need multiple versions to
support deletes properly?").
Reasonable values for the default are 1 and max int. 1 is the better choice.
Discussion on the mailing list suggests that the current value of 3 may have
been derived from an example in the Bigtable paper. The example does not
suggest that there is anything special about 3, it's just an illustration.
