------------------------------------
Summary: Java options being duplicated several times
Key: HADOOP-8448

Project: Hadoop Common

Components: conf
Affects Versions: 1.0.2

Hadoop is running under Pseudo-Distributed mode according to the
http://hadoop.apache.org/common/docs/r1.0.3/single_node_setup.html#PseudoDistributed
Reporter: Evgeny Rusak
After adding the additional java option to the HADOOP_JOBTRACKER_OPTS like the
following
export HADOOP_JOBTRACKER_OPTS="$HADOOP_JOBTRACKER_OPTS -Dxxx=yyy"
and starting the hadoop instance with start-all.sh, the option added is being
attached several times according to the command
ps ax | grep jobtracker
which prints
.....
29824 ? Sl 22:29 home/hduser/apps/jdk/jdk1.7.0_04/bin/java
-Dproc_jobtracker -XX:MaxPermSize=256m -Xmx600m
-Dxxx=yyy -Dxxx=yyy
-Dxxx=yyy -Dxxx=yyy -Dxxx=yyy
-Dhadoop.log.dir=/home/hduser/apps/hadoop/hadoop-1.0.2/libexec/../logs
......
The aforementioned unexpected behaviour causes the severe issue while
specifying "-agentpath:" option, because several duplicating agents being
considered as different agents are trying to be instantiated several times at
once.
