Description

In PHOENIX-6213 we are planning to add cell tags for Delete mutations. After having a discussion with hbase community via dev mailing thread, it was decided that we will pass the tags via an attribute in Mutation object and persist them to hbase via phoenix co-processor. The intention of PHOENIX-6213 is to store metadata in Delete marker so that while running Restore tool we can selectively restore certain Delete markers and ignore others. For that to happen we need to persist these tags in Backup and retrieve them in Restore MR jobs (Import/Export tool).
Currently we don't persist the tags in Backup.
