David Alves resolved KUDU-1908.
-------------------------------
Resolution: Cannot Reproduce
Fix Version/s: 1.3.0
Tried to reproduce this with the sequence of operations in the log and can't
even in kudu as of 1.5 months ago. Closing as can't repro for now. We can
re-open if we ever see it again.
For future reference the branch in which I was testing this can be found at
https://github.com/dralves/kudu/tree/delta-crash-fuzz-itest
Andrew Wong's WIP patch to reproduce it is:
https://gerrit.cloudera.org/#/c/6272/
> Applying deletes and/or reinserts causes a crash
