Uma Maheswara Rao G commented on BOOKKEEPER-240:
------------------------------------------------
Here is the link about Jcarder http://www.jcarder.org/.
I remember there are some bugs related to accuracy in the reports of Jcarder
and Todd updated the patch some where in Github. Let me try to get it.
To run Jcarder :
we can pass this options to our BK as java options, -javaagent:jcarder.jar
It will instrument the code. To generate the cycles, we have to run some tests
on that server code. As a result, cycles will be generated. All may not be
valid ones, we may need to analyse and validate.
see some reports attached in HDFS-1241, HDFS-2229
