[jira] [Created] (KUDU-1537) Exactly-once semantics for DDL operations

Adar Dembo created KUDU-1537:
--------------------------------

             Summary: Exactly-once semantics for DDL operations
                 Key: KUDU-1537
                 URL: https://issues.apache.org/jira/browse/KUDU-1537
             Project: Kudu
          Issue Type: Bug
          Components: master
    Affects Versions: 0.9.1
            Reporter: Adar Dembo


Now that Kudu has a replay cache, we should use it for master DDL operations like CreateTable(), AlterTable(), and DeleteTable(). To do this we'll need to add some client-specific RPC state into the write that the leader master replicates to its followers, and use that state when an RPC is retried.

Some tests (e.g. master-stress-test) have workarounds that should be removed when this bug is fixed.
