Date Thu, 15 Jul 2010 20:25:56 GMT

Suresh Srinivas commented on HADOOP-6859:
-----------------------------------------

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.

that gives summary of operations performed will be useful for tracking file system use.
