-------------------------------------------
Summary: Potential deadlock with namespace reservations in clone
table fate operation
Key: ACCUMULO-2084
URL: https://issues.apache.org/jira/browse/ACCUMULO-2084
Project: Accumulo
Issue Type: Sub-task
Reporter: Christopher Tubbs
Assignee: Christopher Tubbs
Fix For: 1.6.0
Clone table needs to reserve both the source and destination namespace, (as
well as the source tableId) and it needs to do so in a predictable order, not
attempting to grab the second until it gets the first... otherwise, deadlocks
could occur. To ensure ordering, we need to make sure clone table (and other
operations) reserve everything up front, reserving the namespaces first, and
the tables second. The namespaces should be sorted before reserving, to ensure
overlaps with other fate operations do not cause deadlocks.
