Jim Brennan created YARN-8029:
---------------------------------
Summary: YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS should not use
commas as separators
Key: YARN-8029
URL: https://issues.apache.org/jira/browse/YARN-8029
Project: Hadoop YARN
Issue Type: Bug
Components: yarn
Affects Versions: 3.0.0
Reporter: Jim Brennan
The following docker-related environment variables specify a comma-separated
list of mounts:
YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS
YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS
This is a problem because hadoop -Dmapreduce.map.env and related options use
comma as a delimiter. So if I put more than one mount in
YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS the comma in the variable will be treated
as a delimiter for the hadoop command line option and all but the first mount
will be ignored.
