-----------------------------------------
Summary: "Pool is shutdown" error when running Hadoop jobs on Yarn
Key: CASSANDRA-10751
URL: https://issues.apache.org/jira/browse/CASSANDRA-10751
Project: Cassandra
Issue Type: Bug
Environment: Hadoop 2.7.1 (HDP 2.3.2)
Cassandra 2.1.11
Reporter: Cyril Scetbon
Assignee: Alex Liu
Attachments: output.log
Trying to execute a simple CQL3 query in an Hadoop job that runs on Yarn, I get
errors from Cassandra's internal code. It seems that connections are shutdown
but we can't understand why ...
Here are a subtract of the errors. I also add a file with the complete debug
logs.
