Change subject: java: prohibit use of a KuduTable from an unassociated KuduClient ...................................................................... java: prohibit use of a KuduTable from an unassociated KuduClient This fixes a request-tracking issue with the following code anti-pattern in which a KuduTable associated with one client is used to create operations applied to another client's session: KuduClient client1 = KuduClientBuilder....newClient(); KuduTable t = client1.openTable(...); KuduClient client2 = KuduClientBuilder....newClient(); KuduSession s = client2.newSession(); s.apply(t.newUpdate()); This would cause sequence numbers to be generated out of the session's client's RequestTracker, but then marked complete in the operation's client's RequestTracker. This could cause any number of issues: - a cache "hit" on the server side might cause an operation to get an unrelated operation's response - a cache "miss" on the server side might result in an operation incorrectly being marked as already-responded and garbage collected, causing it to fail. This patch adds a Preconditions check for this issue and fixes some tests where it was triggered.
