Classpath should not be part of command line arguments
------------------------------------------------------
Key: HADOOP-6391
URL: https://issues.apache.org/jira/browse/HADOOP-6391
Project: Hadoop Common
Issue Type: Bug
Components: scripts
Reporter: Cristian Ivascu
Because bin/hadoop and bin/hdfs put the entire CLASSPATH in the command line
arguments, it exceeds 4096 bytes, which is the maximum size that ps (or /proc)
can work with. This makes looking for the processes difficult, since the output
gets truncated for all components at the same point (e.g. NameNode,
SecondaryNameNode, DataNode).
The mapred sub-project does not have this problem, because it calls "export
CLASSPATH" before the final exec. bin/hadoop and bin/hdfs should do the same
thing
