Hi, Recently I deployed an Impala(3.2) cluster on aarch64 platform with some modifications, and then ran some big queries that are from TPC-DS. In the meanwhile, I found the memory of Impalad was not released to OS even though the queries were all finished. I looked through the impalad's metrics tab and really can't figure out where these memory(50.33GB) gone. And according to the decription of /memz, it seems the tcmalloc(2.5) had released its memory to OS. Here are the /memz and /metrics info: https://photos.app.goo.gl/1Ze9WGyEuyMSCs6b9 Any tips will be appreciated. Thanks in advance :)
-- 该不该搁下重重的壳 寻找到底哪里有蓝天 随着轻轻的风轻轻的飘 历经的伤都不感觉疼 我要一步一步往上爬 等待阳光静静看着它的脸 小小的天有大大的梦想 重重的壳裹着轻轻的仰望 我要一步一步往上爬 在最高点乘着叶片往前飞 任风吹干流过的泪和汗总有一天我属于我的天 -- 该不该搁下重重的壳 寻找到底哪里有蓝天 随着轻轻的风轻轻的飘 历经的伤都不感觉疼 我要一步一步往上爬 等待阳光静静看着它的脸 小小的天有大大的梦想 重重的壳裹着轻轻的仰望 我要一步一步往上爬 在最高点乘着叶片往前飞 任风吹干流过的泪和汗总有一天我属于我的天
