> There is a parsing error when I gave two or more hdfs namenodes URI separated by commas as the value of key attribute 'security.kerberos.access.hadoopFileSystems'.
>
> For example, I set this key attribute and value like below in flink-conf.yaml,
> {code:java}
> security.kerberos.access.hadoopFileSystems: hdfs://hadoop-nn1.testurl.com:8020,hdfs://hadoop-nn2.testurl.com:8020 {code}
>
> then, the slash "/" is missing in second URI in parsed value
> {code:java}
> hdfs://hadoop-nn1.testurl.com:8020,hdfs:/hadoop-nn2.testurl.com:8020{code}
>

> Received error message is here.
