Hi Xuefu and All,
recently we are doing concurrent testing, we found the submit request are
blocked at the SparkClientFactory.createClient method, and there are a
synchronized lock on the method, i want to know is this lock required ? the
thread which hold this lock is doing rpcServer.registerClient, this is waiting
the AM register back, it will take some time.
So maybe we can think of to remove the synchronized lock. what do you
say?
Thanks & Regards
wen
