             Summary: [ concurrent delete sg ] There are some timeseries that cannot be deleted
                 Key: IOTDB-3044
                 URL: https://issues.apache.org/jira/browse/IOTDB-3044
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Core/Schema Manager
    Affects Versions: 0.14.0-SNAPSHOT
            Reporter: 刘珍

问题描述：
50sg，500 dev, 200000 sensor/dev

show devices的结果输出到dev_name.txt
顺序读取dev_name.txt中的设备名称，一个设备上1次delete 1个ts，10用户并发执行delete。
有的ts delete不掉。
日志中记录delete ts的操作，show timeseries还可以看到：

测试流程
1. 192.168.10.68 机器
benchmark生成元数据。
2. 获取devices （放在${iotdb_dir}）
执行脚本
get_dev_name.sh
#!/bin/bash
./sbin/start-cli.sh  -e "show devices;" |grep root|awk -F '|' '{print $2}' > dev_name.txt

3. 启动并行delete （放在${iotdb_dir}）
cat del_10ts.sh
#!/bin/bash
function delete_ts()
{
   del_ts=$1
   dev_name=$2
   exp_count=$3
   count_ts ${exp_count} ${dev_name}
   ./sbin/start-cli.sh -e "delete timeseries ${del_ts};"
   let exp_count--
   count_ts ${exp_count} ${dev_name}
}

function count_ts()
{
    exp_c_ts=$1
    dev_name=$2
    cur_c_ts=`./sbin/start-cli.sh -e "count timeseries ${dev_name};"|sed -n "4,4p"|awk -F '|' '{print $2}'`
    if [ "${cur_c_ts}" -eq "${exp_c_ts}" ];then
        echo "ok"
    else
        echo "fail. ${dev_name}  ${exp_c_ts} ${cur_c_ts}" >>./fail.log
    fi
}

function execute()
{
    in_file=$1
    i=$2
    exp_count=$3
    n=0
    cat ${in_file} | while read line
    do
       del_ts="${line}.s_${i}"
       dev_name="${line}.*";
       delete_ts ${del_ts} ${dev_name} ${exp_count} &
       let i++
       let n++
       b=$(( $n % 10 ))
       if [ "$b" -eq "0" ];then
          wait
       fi
    done
    wait
}

# 循环几轮
count_ts_base=200000

for loop in {0..99}
do
    idx=$(( $loop * 2000 ))
    execute "dev_name.txt" ${idx} ${count_ts_base}
    let count_ts_base--
done

idx=199999
execute "dev_name.txt" ${idx} ${count_ts_base}

不符合预期的结果会打印到fail.log

根据fail中记录的 ts名称，查看日志，有对应的delete ，show 可以看到没有被delete掉。
