yarn sub pool and autoplacement rule

Explorer

Hello,

            on CDH 5.X seems it's not possible to create an autoplacement rule based on secondary group if it's using also the subpool.

 

In the cloudera documentation it's possible to create placement rule based on root.<SecondaryGroupName>.

 

When you create a sub queue root.poolparent.pool1  the pool name searched by the rule is poolparent.pool1, but

 in Apache Yarn Documentation ( https://hadoop.apache.org/docs/r2.7.1/hadoop-yarn/hadoop-yarn-site/FairScheduler.html#Queue_Access_C... )  shows that a group name with dot "." is translated with "_dot_" . So it's not ok to create a group poolparent.pool1 because it will be translate in "poolparent_dot_pool1"

 

Any idea?

 

Kind Regards
