[GitHub] [shardingsphere-elasticjob] TeslaCN opened a new issue, #2162: NPE may occurred in InstanceService.getAvailableJobInstances

TeslaCN opened a new issue, #2162:
URL: https://github.com/apache/shardingsphere-elasticjob/issues/2162

   ## Bug Report
   
   ### Which version of ElasticJob did you use?
   
   3.0.2
   
   ### Which project did you use? ElasticJob-Lite or ElasticJob-Cloud?
   
   ElasticJob-Lite
   
   ### Expected behavior
   
   No NPE occur.
   
   ### Actual behavior
   
   ```
   java.lang.NullPointerException: null
    at java.io.StringReader.<init>(StringReader.java:50)
    at org.yaml.snakeyaml.reader.StreamReader.<init>(StreamReader.java:56)
    at org.yaml.snakeyaml.Yaml.loadAs(Yaml.java:457)
    at org.apache.shardingsphere.elasticjob.infra.yaml.YamlEngine.unmarshal(YamlEngine.java:50)
    at org.apache.shardingsphere.elasticjob.lite.internal.instance.InstanceService.getAvailableJobInstances(InstanceService.java:72)
   ```
   
   ### Reason analyze (If you can)
   
   The current logic in `getAvailableJobInstances` is not atomic. The instance node may be removed after `getJobNodeChildrenKeys`.
