Yida Wu has uploaded a new patch set (#3). ( http://gerrit.cloudera.org:8080/23881 )
Change subject: IMPALA-14267: Reduce log frequency when dequeuing fails ...................................................................... IMPALA-14267: Reduce log frequency when dequeuing fails When the admission controller fails to dequeue queries, like when at capacity, it logs a message on every retry loop. This can cause excessive logs, like ten per second until queuing timeout. This patch reduces the log frequency to once every 5 seconds using KLOG_EVERY_N_SECS. This prevents too many logs while keeping the message visible when admission control is at capacity. This also changes the dequeuing fails log level from VLOG(1) to INFO because the macro uses a standard log level, but this is safe because the log rate is under control now. Testing: Verified logs are throttled to 5s intervals when the queue is full.
