centos7安装DataX后运行自检脚本报错-在有总bps限速条件下，单个channel的bps值不能为空，也不能为非正数
运行的测试脚本如下：
python /opt/datax/bin/datax.py /opt/datax/job/job.json
job.json内容如下：
{
"job": {
"setting": {
"speed": {
"byte":10485760
},
"errorLimit": {
"record": 0,
"percentage": 0.02
}
},
"content": [
{
"reader": {
"name": "streamreader",
"parameter": {
"column" : [
{
"value": "DataX",
"type": "string"
},
{
"value": 19890604,
"type": "long"
},
{
"value": "1989-06-04 00:00:00",
"type": "date"
},
{
"value": true,
"type": "bool"
},
{
"value": "test",
"type": "bytes"
}
],
"sliceRecordCount": 100000
}
},
"writer": {
"name": "streamwriter",
"parameter": {
"print": false,
"encoding": "UTF-8"
}
}
}
]
}
}具体报错如下图：
查看源码后解决方法如下：
,
"core":{
"transport": {
"channel": {
"speed": {
"byte": 1231412
}
}
}
}
此时再次执行显示成功
