I misunderstood the original question. I understand what you are asking, now. I do not know if there is a way to clear out the old keys. They don't use much storage space so I've never heard of anyone having an issue with that. Michael

Hello, The key version is stored in the metadata so that the client knows which version of the key to request from the KMS. By incrementing the key version, the old (and incorrect) key is not retrieved when decrypting a file encrypted with the new key. By incrementing the key and not reusing key numbers there is less risk of race conditions and makes it clear to the administrator that the key in use has been incremented. Hope that helps, Michael

Hello, You can solve this by using the Maven shade plugin. Take a look at the Cloudera doc https://docs.cloudera.com/runtime/7.2.9/developing-spark-applications/topics/spark-packaging-different-versions-of-libraries-with-an-application.html . Michael

The service principal keys definitely are used to encrypt the service ticket that the client sends to the server to authenticate itself. I'm not 100% sure why it's not showing up in the klist. The short technical answer is that the hadoop CLIs are not using the user key cache to cache the service tickets. If there is a reason why they don't, it's a reason I have forgotten or never knew.

The data node question has been answered, but one tangental comment - you say you are using the Secondary Name Node service. You almost certainly do not want to be using that. You do not get any HA with the SNN. What you probably want is the Standby Namenode. In Cloudera Manager you can enable HA from the HDFS service actions and that will replace your Secondary Name Node with a Standby Name Node.

Can you use sqoop to retrieve the data directly from the database and dump it into Hive? That will solve your delimiter problem.

Where is the data coming from? You could use a binary format like Avro or Parquet if your source system can export that way. If you MUST have a text file with a delimiter, you need a delimiter that is not anywhere in the data.

I would recommend not using CSV in your case. If you have commas in the fields then you can't really delimit them with commas because, as you have noticed, you will have field breaks in the middle of a field. Can you get the source data exported some other way?

Hello, The timeseries API REST endpoint takes a few parameters with the GET method. You can specify from=, end=, and your desiredRollup which has several options from RAW to WEEKLY. Take a look at the API documentation for more details. You can access this from Cloudera Manager by clicking on Support in the upper right hand corner of the screen and then clicking on API Documentation. Hope this helps. Michael
