Hi, I triggered an flink yarn-session on a running Hadoop cluster… and triggering streaming application on that.
But, I see after few days of running without any issues, the flink application which is writing data to hdfs failing with below exception. Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.token.SecretManager$InvalidToken): token (HDFS_DELEGATION_TOKEN token xxxxxx for xxxxxx) can't be found in cache Can someone please help me how I can fix this. Thanks a lot. Regards, Raja.
