Mohammad Kamrul Islam commented on YARN-1622:
---------------------------------------------
Further analysis found the some claims made in the original description are no
longer valid for apache version. The issue #2 and #3 are in our cluster
specific -- not an apache issue.
However, the issue #1 remains valid.
In short, the scope of this JIRA becomes very limited than what I originally
thought.
Will put a simple patch soon.
> 'bin/yarn' command doesn't behave like 'hadoop' and etc.
> ---------------------------------------------------------
>
> Key: YARN-1622
> URL: https://issues.apache.org/jira/browse/YARN-1622
> Project: Hadoop YARN
> Issue Type: Bug
> Components: client
> Affects Versions: 2.2.0
> Reporter: Mohammad Kamrul Islam
> Assignee: Mohammad Kamrul Islam
>
> There are few issues with 'bin/yarn' and 'etc/hadoop/yarn-env.sh'. They are
> loosely related but fixes are minor and will go in the same files. Therefore
> I combined them into one JIRA.
> Issues are:
> 1, bin/yarn has a dangling 'fi' in the last line. Thanks to shell for so
> compliant!
> 2. YARN_ROOT_LOGGER is defined as "INFO, DFRA" in yarn-env.sh. That's why
> 'bin/yarn' command doesn't show (by default) the log messages in client
> window. But when we used 'bin/hadoop', it shows the log correctly (because
> HADOOP_ROOT_LOOGER is "INFO,console" by default). Need to address this
> non-consistent behavior.
> 3. For each client command, yarn creates a log file in $YARN_LOG_DIR/yarn.log
> own by the 'end-user'. In a multi-tenant environment, the second user will
> not be able to create its own yarn.log in the same place causing the
> exception (pasted at the end). By default, it should write to
> $YARN_LOG_DIR/$USER/yarn.log instead.
> Note:
> --------
> I plan to address only #1 and #2 in this JIRA. If we default the
> YARN_ROOT_LOGGER consistent with 'bin/hadoop', the issue #3 will not happen.
> The scope of this JIRA is come close to 'bin/hadoop' behavior.
> Exception:
> log4j:ERROR setFile(null,true) call failed.
