[aarch64-port-dev ] Java defunct

[Cao Hoang Thu]

Hi Andrew,

I rebuilt all, and I ran hadoop test loop
#cd hadoop-1.0.3
#bin/start-all.sh
#bin/hadoop jar hadoop-*examples*.jar teragen 100000000 /user/hduser/terasort-input
#./loop_test.sh

script loop_test.sh

while [ 1 ] ; do
bin/hadoop fs -rmr /user/hduser/terasort-output
bin/hadoop jar hadoop-*examples*.jar terasort /user/hduser/terasort-input /user/hduser/terasort-output
done

I got a process java <defunct> (it ran about 24 hours)

 Please rebuild everything, then give us precise reproducer
 instructions if
 this repeats.
