While it's true LIVY-424 creates a session leak due to REPL leak in Scala it's not the only thing that can. I've run hundreds of simple scala commands and the leak is only mild/moderate. However, some scala commands can be really problematic. For instance
import org.apache.spark.sql._ run this import repeatedly and within only 10s of executions your sessions performance will degrade and eventually run out of memory. ________________________________ From: lk_hadoop <lk_had...@163.com> Sent: Sunday, November 11, 2018 5:37:34 PM To: user Subject: about LIVY-424 [External Email] ________________________________ hi,all: I meet this issue https://issues.apache.org/jira/browse/LIVY-424 , anybody know how to resolve it? 2018-11-12 ________________________________ lk_hadoop
