Subject [jira] [Created] (YARN-9593) Updating scheduler conf with comma in config value fails
Date Sat, 01 Jun 2019 01:03:00 GMT

---------------------------------

             Summary: Updating scheduler conf with comma in config value fails
                 Key: YARN-9593
                 URL: https://issues.apache.org/jira/browse/YARN-9593
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 3.1.2, 3.2.0, 3.0.0, 2.9.0
            Reporter: Anthony Hsu


For example:
{code:java}
$ yarn schedulerconf -update "root.gridops:acl_administer_queue=user1,user2 group1,group2"

Specify configuration key value as confKey=confVal.{code}
This fails because there is a comma in the config value and the SchedConfCLI splits on comma
first, expecting each split to a k=v pair.

void globalUpdates(String args, SchedConfUpdateInfo updateInfo) {
  if (args == null) {
    return;
  }
  HashMap<String, String> globalUpdates = new HashMap<>();
  for (String globalUpdate : args.split(",")) {
    putKeyValuePair(globalUpdates, globalUpdate);
  }
  updateInfo.setGlobalParams(globalUpdates);
}{noformat}
