--------------------------------------
Summary: linux-container-executor segfault with get_user_info(
Key: YARN-11919
URL: https://issues.apache.org/jira/browse/YARN-11919
Project: Hadoop YARN
Issue Type: Bug
Reporter: Edward Capriolo
The code in container executor is slightly different then the recipe in the
documentation. On alpine it repeatedly segfaults
{code:java}
rvn package -Pnative -Dmaven.skip.test=true -DskipTests -Dtar
cp target/native/target/usr/local/bin/container-executor /usr/local/bin/
chmod 6050 /usr/local/bin/container-executor
chgrp hadoop /usr/local/bin/container-executor
chmod 6050 /usr/local/bin/container-executor
/usr/local/bin/container-executor nobody nobody 0
application_1766935260716_0004 container_1766935260716_0004_02_000001
/yarn-root/nm-local-dir/nmPriv
{code}
Result:
{code:java}
edgy
main : command provided 0
main : run as user is nobody
main : requested yarn user is nobody
main : validate_container_id
main : huh
validated command: INITIALIZE_CONTAINER
init : set_user
maybe free_user
going to check user
min id
min id 1000
Get user info
passwd info
got pwd
Segmentation fault (core dumped)
{code}
The code is different slightly then the recipe here:
[https://linux.die.net/man/3/getpwnam_r]
When I replace the recipe the method works on alpine
