URL: https://github.com/apache/hive/pull/3292#issuecomment-1136682080
> @zhengchenyu I am not sure what exactly do you mean by saying the unit
tests are working in your environment. If you check the failed tests you will
see a lot related to the `TestMiniLlapLocalCliDriver`. If you want to run these
tests and update the plans you don't need Jenkins or anything else. You can do
it by following the steps below:
>
> ```
> mvn clean install -DskipTests -Pitests
> cd itests/qtest
> mvn test -Dtest=TestMiniLlapLocalCliDriver -Dtest.output.overwrite
> ```
>
> If you want to run specific tests then you can use the `-Dqfile` option.

@zabetak
In our compile server, I just test the uni-test in this way. Then all pass.
Seems jenkins fail on this scripts.
```
# removes all stdout and err for passed tests
xmlstarlet ed -L -d 'testsuite/testcase/system-out[count(../failure)=0]' -d
'testsuite/testcase/system-err[count(../failure)=0]' `find . -name 'TEST*xml'
-path '*/surefire-reports/*'`
# remove all output.txt files
find . -name '*output.txt' -path '*/surefire-reports/*' -exec unlink "{}" \\;
```
I also execute this scripts, then pass. I don't know the difference between
my compile server and this jenkins pipeline.
Maybe I should setup a whole jenkins pipeline to reproduce this error. But
jenkinsfile on my jenkins server run failed.

> I found an application which is slow in our cluster, because the proccess
> bytes of one reduce is very huge, but only two reduce.
> when I debug, I found the reason. Because in this sql, one big size table
> (about 30G) with few row count(about 3.5M), another small size table (about
> 100M) have more row count (about 3.6M). So JoinStatsRule.process only use
> 100M to estimate reducer's number. But we need to process 30G byte in fact.
