Phabricator updated HIVE-2781:
------------------------------
Attachment: HIVE-2781.D1881.1.patch
toffer requested code review of "HIVE-2781 [jira] HBaseSerDe should allow users
to specify the timestamp passed to Puts".
Reviewers: JIRA
Users may want to specify the timestamp used for Put requests to hbase. Thus
enabling users to have the same timestamp for a single batch of writes. Which
would be useful for a number of things. HCatalog's HBase storageHandler
implementation makes use of this feature to provide users with snapshot
isolation and write transactions. My proposal is to add the timestamp option as
a final static member: public static final long HBASE_PUT_TIMESTAMP =
"hbase.put_timestamp". And passing this value to all the Puts created by
serialize()
TEST PLAN
Added an unit test.
