Hi Team,
We have enabled Atlas in our environment. After that we started getting connection hanging to Hive/HS2/Knox Gateway.
After that followed below link and changed the configuration.
atlas.hook.hive.maxThreads=50 from 5.
atlas.hook.hive.minThreads=5.
Even i checked my user limit for hive it has been set:
root@hostname:~# su - hive $ ulimit -a time(seconds) unlimited file(blocks) unlimited data(kbytes) unlimited stack(kbytes) 8192 coredump(blocks) 0 memory(kbytes) unlimited locked memory(kbytes) 64 process 16000 nofiles 32000 vmemory(kbytes) unlimited locks unlimited
Logs for the same:
