[HBASE-26512] Make timestamp format configurable in HBase shell scan output

• Type: Improvement
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 3.0.0-alpha-1
• Fix Version/s: 2.5.0, 3.0.0-alpha-2, 2.4.9
• Component/s: shell
• Hadoop Flags: Reviewed

Release Note

HBASE-23930 changed the formatting of the timestamp attribute on each Cell as displayed by the HBase shell to be formatted as an ISO-8601 string rather that milliseconds since the epoch. Some users may have logic which expects the timestamp to be displayed as milliseconds since the epoch. This change introduces the configuration property hbase.shell.timestamp.format.epoch which controls whether the shell will print an ISO-8601 formatted timestamp (the default "false") or milliseconds since the epoch ("true").

Description

HBASE-23930 and HBASE-24937 has changed the timestamp format shown in scan results in HBase shells.

This may break existing use cases that use hbase shell as a client. (as opposed to the java, rest, or thrift APIs)

I propose adding a configuration option to make it configurable.
