• Type: Bug

Description

For long running jobs I have hit an issue that seems to be to be similar to the bug reported in https://issues.apache.org/jira/browse/MAPREDUCE-3583

Unfortunately I do not have the OS logs for this issue, but the utime for the application was read by Hadoop as "184467440737095551615" which does not fit into a Long. In MAPREDUCE-3583 a change was made to ProcfsBasedProcessTree.java
in order to support larger values for stime. Perhaps we need to support larger values for utime (although this could increase the complexity of the math that is being performed on those numbers)
