Open Source Presto Releases & Features ⬆️

We had a great start to the month with release 0.263, the top features of the month are: 

Add support to perform heapDump on exceeded memory limit failures which supports an ability to trigger a heap dump in exceeded_memory_limit failure cases. This will greatly improve debugging experiences around query OOMs. Shout out to Arjun Gupta pgupta2 for contribution!

Implement key-based sampling in the planner with this feature enabled, Presto traverses the plan for the query and samples the first integer or string key found. This helps users to get a sense of the results for queries which are running on large datasets that keep failing/running for a long time/timing out. Thanks, Sreeni Viswanadha kaikalur for the contribution!

Thanks so much for your continued support! We hope you enjoyed these updates. See you in the Slack channel.

Re: Presto - Hive connector - Unable to query the data from hdfs encryption zones


Hi Team,

Could you please share an update if we have any ways to query data from hdfs encyption zones. 


Presto - Hive connector - Unable to query the data from hdfs encryption zones


Hi Team,


We did the presto setup (version – 0.253) on one coordinator (master node), 7  worker nodes (data nodes) and presto CLI on the edge node of the Cloudera CDH cluster – 6.2.1.


We are able to run the presto queries against the data present in Hadoop via hive connector.


We are getting the below issue when running the queries against the data present in hdfs encryption zones (Key Trustee KMS) – Data at rest.


Failed: Error opening the Hive split hdfs://<path>: No KeyProvider is configured, cannot access an encrypted file.

Caused by No KeyProvider is configured, cannot access an encrypted file.


Could not find the relevant property in the hive connector section of the Presto documentation. (could this be a limitation.. I doubt).


Could you please let me know if you come across this problem and solutions in any of your implementations.


Appreciate your inputs and happy to get connected and discuss in details.


Thank you in advance..
