YarnConfiguration
Field NM_LINUX_CONTAINER_GROUP of type java.lang.String with the compile-time constant value "yarn.nodemanager.linux-container-executor.group" has been removed from this class.
- Package Name
- org.apache.hadoop.yarn.conf
- Effect
- Recompilation of a client program may be terminated with the message: cannot find variable NM_LINUX_CONTAINER_GROUP in org.apache.hadoop.yarn.conf.YarnConfiguration.
- Reason for change
- YARN-4599 removed this unused variable. It seems unrelated to the change itself.
- Recommendation
- Details about this config option: The UNIX group that the linux-container-executor should run as. This is intended to be set as part of container-executor.cfg. If a YARN client needs this variable it shall be created manually: public static final String NM_LINUX_CONTAINER_GROUP=""yarn.nodemanager.linux-container-executor.group"";.
- Recompilation Required?
- Yes
