Phabricator updated HIVE-2781:
------------------------------
Attachment: HIVE-2781.D1863.1.patch
navis requested code review of "HIVE-2781 [jira] HBaseSerDe should allow users
to specify the timestamp passed to Puts".
Reviewers: JIRA
DPAL-861 HBaseSerDe should allow users to specify the timestamp passed to Puts
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()
