Xiaoqiao He commented on HDFS-16067:
------------------------------------

Thanks [~prasad-acit] for your update.
{quote}A. Regarding Prepare Fileset: AppendFileStats extends OpenFileStats, so 
generateInputs() is being called from the base 
classOperationStatsBase#benchmark(). Please correct me if i missed something 
from your point.{quote}
it makes sense to me.
A. Seems that "<p>" is not necessary here.
{code:java}
+  /**
+   * Append file statistics.
+   * <p>
+   * Measure how many append calls the name-node can handle per second.
+   */
{code}
B. Please check the failed unit tests. + I try to trigger Jenkins manually. 
Let's wait what it says.
