--------------------------------------------
Summary: fix mvn compile -Pnative on CentOS / RHEL / Fedora / SuSE
/ etc
Key: HADOOP-8499
URL: https://issues.apache.org/jira/browse/HADOOP-8499
Project: Hadoop Common
Issue Type: Bug
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
On Linux platforms where user IDs start at 500 rather than 1000, the build
currently is broken. This includes CentOS, RHEL, Fedora, SuSE, and probably
most other Linux platforms. It does happen to work on Debian and Ubuntu, which
explains why Jenkins hasn't caught it yet.
Other users will see something like this:
{code}
[INFO] Requested user cmccabe has id 500, which is below the minimum allowed
1000
[INFO] FAIL: test-container-executor
[INFO] ================================================
[INFO] 1 of 1 test failed
[INFO] Please report to mapreduce-...@hadoop.apache.org
[INFO] ================================================
[INFO] make[1]: *** [check-TESTS] Error 1
[INFO] make[1]: Leaving directory
`/home/cmccabe/hadoop4/hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn
-server/hadoop-yarn-server-nodemanager/target/native/container-executor'
{code}
And then the build fails. Since native unit tests are currently unskippable
(HADOOP-8480) this makes the project unbuildable.
The easy solution to this is to relax the constraint for the unit test. Since
the unit test already writes its own configuration file, we just need to change
it there.
In general, I believe that it would make sense to change this to 500 across the
board. I'm not aware of any Linuxes that create system users with IDs higher
than or equal to 500. System user IDs tend to be below 200.
However, if we do nothing else, we should at least fix the build by relaxing
the constraint for unit tests.
