Junping Du commented on YARN-6877:
----------------------------------

It is very tricky to find out real errors among thousands of ERROR messages, but I think finally
I found two that is really error:

{code}
...
[ERROR] /testptch/hadoop/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/logaggregation/filecontroller/LogAggregationFileController.java:231:
error: @param name not found
[ERROR] * @param the aggregatedLog path.
...
[ERROR] /testptch/hadoop/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/logaggregation/filecontroller/LogAggregationFileController.java:242:
error: @param name not found
[ERROR] * @param the aggregatedLog path.
{code}

[~xgong], can you double check any other java doc errors?

> Currently, TFile log reader is used to read aggregated log in YARN. We need to add an
abstract layer, and pick up the correct log reader based on the configuration.
