Provider org.apache.hadoop.fs.sftp.SFTPFileSystem not found

**版本**：v.1.12.1
以yarn-per-job运行，
```
bin/flinkx -mode yarn-per-job -jobType sync -job flinkx-examples/json/stream/stream.json -flinkxDistDir /opt/chunjun/flinkx-dist/ -flinkConfDir /etc/flink/conf -hadoopConfDir /etc/hadoop/conf -flinkLibDir /opt/cloudera/parcels/FLINK/lib/flink/lib
```
报错如下：
