Hi Patrick, When this has happened to me in the past (admittedly via spark-submit) it has been because another job was still running and had already claimed some of the resources (cores and memory).
I think this can also happen if your configuration tries to claim resources that will never be available.

The cluster has 64 cores, 250GB RAM, and operates in standalone mode using HDFS for storage. The query is as follows: SELECT ME.*, MB.BenefitID FROM MemberEnrollment ME JOIN MemberBenefits MB ON ME.ID<http://me.id/> = MB.EnrollmentID WHERE MB.BenefitID = 5 LIMIT 10 The tables are defined as follows: -- Contains about 3M rows CREATE TABLE MemberEnrollment ( ID INT , MemberID VARCHAR(50) , StartDate DATE , EndDate DATE -- Other columns, but these are the most important ) STORED AS ORC; -- Contains about 25m rows CREATE TABLE MemberBenefits ( EnrollmentID INT , BenefitID INT ) STORED AS ORC; When I execute the query, it runs a single broadcast exchange stage, which completes after a few seconds. Then everything just hangs. The JDBC/ODBC tab in the UI shows the query state as COMPILED, but no stages or tasks are executing or pending: <image.png> I've let the query run for as long as 30 minutes with no additional stages, progress, or errors. I'm not sure where to start troubleshooting. Thanks for your help, Patrick This email contains confidential information of and is the copyright of Infomedia.
