Date Tue, 20 Sep 2016 17:23:20 GMT

     [ https://issues.apache.org/jira/browse/YARN-3141?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Wangda Tan updated YARN-3141:
-----------------------------
    Attachment: YARN-3141.addendum-0.patch

Ah my bad, there's one line change which causes javadocs fail.

There're tons of message in javadocs building which start with "[ERROR]", however most of
them are warnings, the real error message submerged in these output:

bq. [ERROR] /Users/wtan/project/github/hadoop-common-trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/common/fica/FiCaSchedulerApp.java:331:
error: @param name not found

Uploaded addendum-0 patch.

> Enhance locks in SchedulerApplicationAttempt/FSAppAttempt/FiCaSchedulerApp, as mentioned
in YARN-3091, a possible solution is using read/write lock. Other fine-graind locks for specific
purposes / bugs should be addressed in separated tickets.
