> Java options being duplicated several times
> -------------------------------------------
>
> Key: HADOOP-8448
> URL: https://issues.apache.org/jira/browse/HADOOP-8448
> Project: Hadoop Common
> Issue Type: Bug
> Components: conf, scripts
> Affects Versions: 1.0.2
> Environment: VirtualBox 4.1.14 r77440
> Linux slack 2.6.37.6 #3 SMP Sat Apr 9 22:49:32 CDT 2011 x86_64 Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz GenuineIntel GNU/Linux
> java version "1.7.0_04"
> Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
> Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)
> Hadoop 1.0.2
> Subversion https://svn.apache.org/repos/asf/hadoop/common/branches/branch-1.0.2 -r 1304954 Compiled by hortonfo on Sat Mar 24 23:58:21 UTC 2012
> From source with checksum c198b04303cfa626a38e13154d2765a9
> 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
> .....

> -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.
