--------------------------------
Summary: Transaction manager should use RDBMS time instead of
machine time
Key: HIVE-6965
URL: https://issues.apache.org/jira/browse/HIVE-6965
Project: Hive
Issue Type: Bug
Components: Locking
Affects Versions: 0.13.0
Reporter: Alan Gates
Assignee: Alan Gates
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.
