> 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.
