问题描述：An error occurred: Error while processing samples:Mismatch between expected number of columns:17 and columns in CSV file:14, check your jmeter.save.saveservice.* configuration or check line is complete
最近在稳定性测试时，我使用了nohup挂载jmx进行测试24h
nohup jmeter -n -t chenbean.jmx -l 100th24h.csv -e -o 100th24h > 24hnohup.csv 2>&1 &
但是第二天我上去看发现我自动生成 报告失败了，所以我打算手动根据已有的csv生成html报告试下：
jmeter -g 100th24h.csv -e -o resultdir
结果还是报错：
An error occurred: Error while processing samples:Mismatch between expected number of columns:17 and columns in CSV file:14, check your jmeter.save.saveservice.* configuration or check line is complete
意思是我要求有17列解析，却发现你一行只有14列：
我就vi 进入csv最后查看：结果如下
1589930374049,1220,Java Request,0,success,Thread Group 1-45,text,true,,47231,0,55,55,null,0,0,0
1589930374050,1220,Java Request,0,success,Thread Group 1-25,text,true,,47213,0,55,55,null,0,0,0
1589930373938,1439,Java Request,0,success,Thread Group 1-54,text,true,,47237,0,53,53,null,0,0,0
1589930374031,1349,Java Request,0,success,Thread Group 1-41,text,true,,47219,0,52,52,null,0,0,0
1589930374238,1146,Java Request,0,success,Thread Group 1-44,text,true,,47223,0,51,51,null,0,0,0
1589930374391,986,Java Request,0,success,Thread Group 1-7,text,true,,47255,0,53,53,nul
明显最有一行null开始就写入有问题了导致后几列都没写入，至此破案了删掉最后一行重新执行 jmeter -g 100th24h.csv -e -o resultdir
问题解决
