Matthew Jacobs commented on KUDU-1745:
--------------------------------------
FYI, I filed https://issues.cloudera.org/browse/IMPALA-4478 to track work for
Impala to account for Kudu client memory in its own memory accounting
mechanism. If we do that, we probably shouldn't run out of memory. We can
easily account for the mutation buffer space. I think we may be in trouble now
though since the memory required for errors is currently unbounded. That's just
one thing that comes to mind, we may need to think about other sources of
potentially large amounts of memory we need to bound and/or account for.
