Large read operation is left to the file system implementation. I am explaining that in the context of HDFS in this jira. I have it also documented in javadoc for getLargeReadOps() method.

Suresh Srinivas commented on HADOOP-6859:
-----------------------------------------
I am planning to introduce the following additional statistics, that is accumulated at the client per file system as it is done now.
# read operations - number of read operations such as listStatus, getFileBlockLocations, open etc.
# write operations - number of write operations such as create, append, setPermission etc.
# large read operations - on file system, most of the operations are small except listFiles for a large directory. Iterative listFiles was introduced in HDFS to break down a single large operation into smaller steps. This counter is incremented is incremented for every iteration of listFiles, when listing files under a large directory.
These statistics are collected in job history for analysis of how HDFS is loaded by map reduce tasks. This is useful in the interim to identify jobs that heavily load HDFS. In future this could also be used to throttle the load at the map reduce framework.

Patch looks fine. You might want to mention in the javadoc what you mentioned here in the JIRA about what a "large read" operation may be.
