[Thrift2] TDelete.deleteType defaults to TDeleteType.DELETE_COLUMNS, but the
docs suggest otherwise
---------------------------------------------------------------------------------------------------
Key: HBASE-5761
URL: https://issues.apache.org/jira/browse/HBASE-5761
Project: HBase
Issue Type: Bug
Reporter: Wouter Bolsterlee
It seems to me there is an inconsistency (or error) in the Thrift2 {{TDelete}}
struct and its documentation. The docs for the {{TDelete}} struct state:
{quote}
If no timestamp is specified the most recent version will be deleted. To
delete all previous versions, specify the DELETE_COLUMNS TDeleteType.
{quote}
...which implies that the default is {{TDeleteType.DELETE_COLUMN}} (singular),
not {{TDeleteType.DELETE_COLUMNS}} (plural).
However, the {{deleteType}} field in the {{TDelete}} struct defaults to the
value {{1}}, which is {{TDeleteType.DELETE_COLUMNS}} (plural) in
{{/src/main/resources/org/apache/hadoop/hbase/thrift2/hbase.thrift}}. The field
is currently (r1239241) defined as follows:
{{ 4: optional TDeleteType deleteType = 1,}}
I'd suggest that the default for this optional field is changed to
{{TDeleteType.DELETE_COLUMN}} (singular). The line above from the {{TDelete}}
struct would then become:
{{ 4: optional TDeleteType deleteType = 0,}}
Since this change just involves changing a {{1}} into a {{0}}, I'll leave the
trivial patch to someone who can also commit it in one go. Thanks in advance. :)
