Hello Adar Dembo, Alexey Serbin, Kudu Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/4949
to look at the new patch set (#3).
Change subject: [java client] Redirect KuduExceptions to RowError in KuduSession
......................................................................
[java client] Redirect KuduExceptions to RowError in KuduSession
Currently the only RowErrors that the users were going to see were the ones
sent from the tablet servers. Any other client-side error was sent as an
exception, even timeouts. The other problem with timeouts is that, when using
AUTO_FLUSH_BACKGROUND, background flush responses that the client isn't waiting
on would get lost since we don't have an equivalent to the error collector
for exceptions. You could find them in the log, but that's it.
This patch augments one of the errbacks in AsyncKuduSession to start creating
OperationResponses for KuduExceptions. For those cases, we return a
List<OperationResponses> which switches us from the _errback_ to the _callback_
track. Other exceptions are sent straight back.
This patch also makes some changes for an issue that Adar saw in
TestAsyncKuduSession
that was kind of hard to debug, a stray buffer was being flushed against a
table that
was deleted (but then the table's name was reused which made reading the logs
harder).
The stray buffer most likely came from testBatchErrorCauseSessionStuck which
isn't
checking for all the error conditions. This patch adds more checking but
doesn't fix
the root cause (which is currently unknown) so it *may* make it fail more often,
but in more obvious ways.
