　　实在不知道是啥原因， 求达人指教.
　　写法一:
　　for i in seq `1 3`;
do hadoop jar hadoop-test-1.0.3.jar mrbench -inputLines 80000 -maps 300 -reduces 30 >/opt/jobs/mrbench$i.txt 2>&1 &;
hadoop jar hadoop-examples-1.0.3.jar pi 500 200000000 > /opt/jobs/pi$i.txt 2>&1 & ;
hadoop fs -rmr /user/liuqiang/Pi*;
done
　　报错: ./mixed_jobs.sh: line 12: syntax error near unexpected token `;'
./mixed_jobs.sh: line 12: `do hadoop jar hadoop-test-1.0.3.jar mrbench -inputLines 80000 -maps 300 -reduces 30 >/opt/jobs/mrbench$i.txt 2>&1 &;'
　　
　　
　　写法二:
for i in seq `1 3`;
do
"hadoop jar hadoop-test-1.0.3.jar mrbench -inputLines 80000 -maps 300 -reduces 30 >/opt/jobs/mrbench$i.txt 2>&1 &;
　　hadoop jar hadoop-examples-1.0.3.jar pi 500 200000000 > /opt/jobs/pi$i.txt 2>&1 & ;
　　hadoop fs -rmr /user/liuqiang/Pi*";
done
　　报错:
　　./mixed_jobs.sh: line 13: 1: command not found
./mixed_jobs.sh: line 12: hadoop jar hadoop-test-1.0.3.jar mrbench -inputLines 80000 -maps 300 -reduces 30 >/opt/jobs/mrbenchseq.txt 2>&1 &;hadoop jar hadoop-examples-1.0.3.jar pi 500 200000000 > /opt/jobs/piseq.txt 2>&1 & ; hadoop fs -rmr /user/liuqiang/Pi*:No such file or director
　　
　　写法三:
　　
for i in seq `1 3`;
do
`hadoop jar hadoop-test-1.0.3.jar mrbench -inputLines 80000 -maps 300 -reduces 30 >/opt/jobs/mrbench$i.txt 2>&1 &;
　　hadoop jar hadoop-examples-1.0.3.jar pi 500 200000000 > /opt/jobs/pi$i.txt 2>&1 & ;
　　hadoop fs -rmr /user/liuqiang/Pi* `;
done
　　报错:
　　./mixed_jobs.sh: line 13: 1: command not found
./mixed_jobs.sh: command substitution: line 12: syntax error near unexpected token `;'
./mixed_jobs.sh: command substitution: line 12: `hadoop jar hadoop-test-1.0.3.jar mrbench -inputLines 80000 -maps 300 -reduces 30 >/opt/jobs/mrbench$i.txt 2>&1 &;hadoop jar hadoop-examples-1.0.3.jar pi 500 200000000 > /opt/jobs/pi$i.txt 2>&1 & ; hadoop fs -rmr/user/liuqiang/Pi* '
　　
　　写法四:
　　for i in seq `1 3`;
do
`hadoop jar hadoop-test-1.0.3.jar mrbench -inputLines 80000 -maps 300 -reduces 30 >/opt/jobs/mrbench$i.txt 2>&1 &
　　hadoop jar hadoop-examples-1.0.3.jar pi 500 200000000 > /opt/jobs/pi$i.txt 2>&1 &
　　hadoop fs -rmr /user/liuqiang/Pi* `;
done
　　报错:
　　./mixed_jobs.sh: line 13: 1: command not found
