---------------------------------------
Summary: YARN fails to create containers if Bash functions
exported in environment
Key: IGNITE-7080
URL: https://issues.apache.org/jira/browse/IGNITE-7080
Project: Ignite
Issue Type: Bug
Components: yarn
Affects Versions: 2.3
Reporter: Ilya Kasnacheev
Assignee: Ilya Kasnacheev
Ignite YARN collects all existing environment variables to pass them to
container, including variables with incorrect names, such as Bash functions,
which have extra characters at the end, and are ignored by most shells but not
the JVM.
When you tell Bash to export functions, it puts BASH_FUNC_your_function_name%%
variable into env. This is what is causing problems because Ignite YARN picks
this variable and tells Hadoop to pass it to container, which leads to
incorrectly written startup scrips.
Hadoop tries to sanitize env var values but not env var names. I think Ignite
should not try to pass all env vars to containers (it may contain sensitive or
master-specific vars!). We should only pass env vars that are relevant to
containers, such as IGNITE_* vars.
