[jira] [Commented] (IMPALA-10216)
BufferPoolTest.WriteErrorBlacklistCompression is flaky on UBSAN builds
[ https://issues.apache.org/jira/browse/IMPALA-10216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17237747#comment-17237747 ]
Fang-Yu Rao commented on IMPALA-10216:
--------------------------------------
We found in a recent TSAN build that {{BufferPoolTest.WriteErrorBlacklistHolepunch}} failed on {{FindPageInDir}} check at [https://github.com/apache/impala/blob/master/be/src/runtime/bufferpool/buffer-pool-test.cc#L1792].
The error message we saw in the console output is in the following.
{noformat}
22:29:36 Value of: FindPageInDir(pages[NO_ERROR_QUERY], error_dir) != NULL
22:29:36 Actual: false
22:29:36 Expected: true

In {{buffer-pool-test.ERROR}} we saw quite a few Disk I/O errors, each being followed by an access denied error.
The corresponding error logs are also provided.
