[BUG] Error occurred in DefaultStreamLoader#getAvailableHost while trying to load a URL due to configuration issues. #367
Description
When configuring the load URL value, I mistakenly used a comma instead of a semicolon, like this : 10.x.x.1:8030,10.x.x.2:8030,10.x.x.3:8030.
except: throw an exception while flink start failed
acture: only log error, flink application is running available
I found two point can be optimized.
DefaultStreamLoader#testHttpConnectioncatched all Exception at now, wo can catchMalformedURLExceptionand throw anIllegalArgumentException.StarRocksSinkOptions#validateStreamLoadUrlshould be enhance.
