I start up LLAP with slider,and the shell command is
"hive2 --service llap -name llap_service -instances 5 -size 5g -loglevel INFO -args "-XX:MaxMetaspaceSize=128m -verbose:class -XX:+UseParNewGC -Xmn1g -XX:+UseConcMarkSweepGC -XX:+UseBiasedLocking -XX:+PerfDisableSharedMem" -cache 3g -executors 30 -iothreads 10 -slider-am-container-mb 3096
"
and then start LLAP with "llap-slider-07Aug2019/run.sh",logs like this:

then look into yarn application and hive-ui:



I have no idea why there is just one LLAP Daemon and "Live Instances" is zero? beacause the log of LLAP container indicates it is successfully started:

P.S.
my env: hive-2.3.0 hadoop-2.7.1 tez-0.9.2 slide-0.92.0
Does someone met the same question or have an idea?
Thanks.
