ASF subversion and git services commented on KUDU-3384: ------------------------------------------------------- Commit 6fe47b5ecc5bdafdb17aa7722d296c4e5d4d32bf in kudu's branch refs/heads/master from Alexey Serbin [ https://gitbox.apache.org/repos/asf?p=kudu.git;h=6fe47b5ec ] KUDU-3384 reproduction scenario This patch contains a new test scenario to reproduce KUDU-3384. The new test is disabled since it fails pretty reliably, at least if built in DEBUG configuration.

See [this gerrit review > item|http://gerrit.cloudera.org:8080/18757] for the reproduction scenario. -- This message was sent by Atlassian Jira (v8.20.10#820010)
