Abhishek Rawat updated IMPALA-14497:
------------------------------------
Description:
Admissiond's memory usage could grow with higher concurrency and longer
admission queue length. We should add tcmalloc flags similar to impalads to
tune memory footprint for admissiond.
# `tcmalloc_max_total_thread_cache_bytes` should be added so that we can tune
them
# `aggressive_memory_decommit` should be enabled by default similar to
impalads.
