Subject [jira] [Created] (HADOOP-8448) Java options being duplicated several times
Date Wed, 30 May 2012 09:32:23 GMT
Evgeny Rusak created HADOOP-8448:
------------------------------------

             Summary: 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
    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"

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.
