---------------------------------------------------
Summary: ProcfsBasedProcessTree#constructProcessInfo() can still
throw NumberFormatException
Key: MAPREDUCE-5715
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5715
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 2.2.0, trunk
Environment: Ubuntu 13.04 (OS Kernel 3.9.0), Armv71Exynos5440
Reporter: German Florez-Larrahondo
Priority: Minor
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)
