Slow Get performance, is there a way to profile a Get?

[Jeff Whiting]

Is there way to profile a specific get request to see where the time is spent (e.g. checking 
memstore, reading from hdfs, etc)?

We are running into a problem where a get after a delete goes really slow.  We have a row that has 
between 100 to 256 MB of data in it across a couple hundred columns.  After putting the data we can 
get the data out quickly (< 100ms).  So a get on "info:name" will take ~0.05110 seconds according 
the hbase shell. We then delete the entire row (e.g. htable.delete(new Delete(rowkey)).  Most of the 
time after deleting the row trying the exact same get on "info:name" becomes significantly slower 
(1.9400 to 3.1840 seconds).  Putting data back into "info:name" still results in the same slow 
performance.  I was hoping to profile the get to see where the time is going and seeing what we can 
do to tune how we are using hbase.

Thanks,
