Hadoop Trash Folder Size

[#1]

What is the most efficient way to determine the size of Trash in a cluster periodically?  It seems like this is not available through the Hadoop metrics.

You are right, I don't see this in hadoop metrics or in jmx stats in  the active namenode on my clusters either. 

here is a way to get what you are after in hdfs commands:

hdfs dfs -du /user/*/.Trash
