[jira] [Created] (KUDU-2131) Tablet copy session may expire before completion for large tablet

Hao Hao created KUDU-2131:
-----------------------------

             Summary: Tablet copy session may expire before completion for large tablet
                 Key: KUDU-2131
                 URL: https://issues.apache.org/jira/browse/KUDU-2131
             Project: Kudu
          Issue Type: Bug
            Reporter: Hao Hao
            Priority: Blocker
             Fix For: 1.5.0


KUDU-1726 introduced an optimization to do a bulk sync-to-disk once the tablet copy operation is complete. However, when tested in a large cluster, I found disk synchronization in batches can result in the tablet session expires before the synchronization complete. There is a flag '--tablet_copy_idle_timeout_ms' to control the amount of time without activity before a tablet copy session expires, but it is tagged as hidden(not user-facing).
