问题描述 ：
0.13.0 rc1 每个sg的合并任务分布不均匀。

复现流程：
长测配置，顺序数据。
启动测试后，运行脚本：
cat get_sg_tsfile-count.sh
#!/bin/bash
sg_res=" "
function sg_tsfile()
{
tsfile_count=`ls -l /data/iotdb_data/data/sequence/root.test.g_${1}/0/0/*.resource|wc -l`
sg_res="${sg_res} ${tsfile_count}"
}

while true
do
for i in

{0..49}

do
sg_tsfile ${i}
done
time=`date "+%Y-%m-%d %H:%M:%S"`
echo "${time} ${sg_res} " >> sg_tsfile_res_0509.out
sleep 2h
sg_res=" "
done
