We have enabled KMS in our server, after enabling KMS and encryption , we are getting following error randomly , Is there anything we can try to resolve this issue ?
org.apache.spark.SparkException: Job aborted due to stage failure: Task 58 in stage 12.0 failed 4 times, most recent failure: Lost task 58.3 in stage 12.0 (TID 4151, lpdn0307.): java.io.IOException: java.lang.IllegalArgumentException: java.net.UnknownHostException: edhpen1262 at org.apache.hadoop.crypto.key.kms.KMSClientProvider
We verified the DNS resolution and hostname , everything is looking good.
What else may be the issue.
