Konstantin Shvachko updated HDFS-1361:
--------------------------------------
Attachment: NNThroughput-fileStatus.patch
The patch introduces -fileStatus operation. It is run similar to open or delete
ops.
I also converted TestNNThroughputBenchmark to a Junit-4 test and added a
description of "advanced" options to JavaDoc.
This benchmark was used to compare performance of debug() messages in
HADOOP-6884.
