My Giraph jobs hang, and the logs are given at the bottom of this e-mail. This is same as JIRA - GIRAPH-806.
I observed that there is a patch available for this problem: But when I try to apply the patch on top of Giraph 1.0.0: I face the problem that the patch has been provided on a nightly build dated ---> 1390205044000 ( I did not understand this date format), and not on Giraph 1.0.0. What should I do now?Someone please help....
