Description

If configure file not found, or lost nessary configure urls, then a exception happens as following :

{{2021-04-27 10:46:30,658 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: Failed to start namenode.
java.lang.IllegalArgumentException: bound must be positive
at java.util.Random.nextInt(Random.java:388)

at org.apache.ranger.admin.client.RangerAdminRESTClient.init(RangerAdminRESTClient.java:778)
at org.apache.ranger.admin.client.RangerAdminRESTClient.init(RangerAdminRESTClient.java:116)}}

 

Maybe, we should add a pre-check.
