sf_tree_seg分支 eadb383df889a7040b30f75ee443c2a8552856d5
单机版
改一下并发创建元数据的脚本（加2行echo "hello"）：
#!/bin/bash
time1=`date +%s`
cp -rp conf/config.properties.1 conf/config.properties
./benchmark.sh > 1.out &
echo "hello"
echo "hello"
cp -rp conf/config.properties.2 conf/config.properties
./benchmark.sh > 2.out &
wait
time2=`date +%s`
time=$(($time2-$time1))
echo "bing fa run : ${time} seconds." >> time_res.txt
还有如下异常：
