Hao, thank you so much for the reply! Do you already have some JIRA for the discussion?

Currently, each SQLContext has its own configuration, e.g. shuffle partition number, codegen etc. and it will be shared among the multiple threads running. We actually has some internal discussions on this, probably will provide a "thread local" configuration in the future for a single SQLContext instance. -----Original Message----- From: Haopu Wang [mailto:hw...@qilinsoft.com] Sent: Tuesday, March 3, 2015 7:56 AM To: Cheng, Hao; user Subject: RE: Is SQLContext thread-safe? Thanks for the response. Then I have another question: when will we want to create multiple SQLContext instances from the same SparkContext? What's the benefit? -----Original Message----- From: Cheng, Hao [mailto:hao.ch...@intel.com] Sent: Monday, March 02, 2015 9:05 PM To: Haopu Wang; user Subject: RE: Is SQLContext thread-safe? Yes it is thread safe, at least it's supposed to be. -----Original Message----- From: Haopu Wang [mailto:hw...@qilinsoft.com] Sent: Monday, March 2, 2015 4:43 PM To: user Subject: Is SQLContext thread-safe? Hi, is it safe to use the same SQLContext to do Select operations in different threads at the same time? Thank you very much! --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
