> Current TxnHandler and CompactionTxnHandler use System.currentTimeMillis()
> when they need to determine the time (such as heartbeating transactions). In
> situations where there are multiple Thrift metastore services or users are
> using an embedded metastore this will lead to issues. We should instead be
> using time from the RDBMS, which is guaranteed to be the same for all users.
