Review Comment:
This change was made because the `ResourceManager` module in #7335 reported
an `unable to create new native thread` exception. Additionally, the third
build result of #7335 appeared abnormal, and I suspected that the issue might
be caused by the large number of compiled modules. I increased the `-Xss` size,
which seemed to have some effect. The default value for this parameter is 1m.
The build report is as follows:
https://ci-hadoop.apache.org/job/hadoop-multibranch/job/PR-7335/3/artifact/out/patch-unit-hadoop-yarn-project_hadoop-yarn_hadoop-yarn-server_hadoop-yarn-server-resourcemanager.txt
If either #7343 or #7335 is merged, the other PR can remove this change.
