It's clear this is a problem, as the method has code to > detect timeouts in the window and warn of problems. > It should be possible to make this faster -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
