[jira] [Commented] (YARN-9519) TFile log aggregation file format is insensitive to the yarn.log-aggregation.TFile.remote-app-log-dir config

    [ https://issues.apache.org/jira/browse/YARN-9519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16832469#comment-16832469 ] 

Adam Antal commented on YARN-9519:
----------------------------------

Uploaded patch v2 with some tests.

Unfortunately I couldn't touch the tests without refactoring it a bit. Could you please also check on the tests as well [~snemeth]?

> The TFile log aggregation file format is not sensitive to the yarn.log-aggregation.TFile.remote-app-log-dir config.
> In {{LogAggregationTFileController$initInternal}}:
> {code:java}
>     this.remoteRootLogDir = new Path(
>         conf.get(YarnConfiguration.NM_REMOTE_APP_LOG_DIR,
>             YarnConfiguration.DEFAULT_NM_REMOTE_APP_LOG_DIR));
> {code}
> So the remoteRootLogDir is only aware of the yarn.nodemanager.remote-app-log-dir config, while other file format, like IFile defaults to the file format config, so its priority is higher.
> From {{LogAggregationIndexedFileController$initInternal}}:
> {code:java}
>     String remoteDirStr = String.format(
>         YarnConfiguration.LOG_AGGREGATION_REMOTE_APP_LOG_DIR_FMT,
>         this.fileControllerName);
>     String remoteDir = conf.get(remoteDirStr);
>     if (remoteDir == null || remoteDir.isEmpty()) {
>       remoteDir = conf.get(YarnConfiguration.NM_REMOTE_APP_LOG_DIR,
>           YarnConfiguration.DEFAULT_NM_REMOTE_APP_LOG_DIR);
>     }
> {code}
> (Where these configs are: )
> {code:java}
> public static final String LOG_AGGREGATION_REMOTE_APP_LOG_DIR_FMT
>       = YARN_PREFIX + "log-aggregation.%s.remote-app-log-dir";
> public static final String NM_REMOTE_APP_LOG_DIR = 
>     NM_PREFIX + "remote-app-log-dir";
> {code}
> I suggest TFile should try to obtain the remote dir config from yarn.log-aggregation.TFile.remote-app-log-dir first, and only if that is not specified falls back to the yarn.nodemanager.remote-app-log-dir config.
