CDH 6.2.1 Impala daemon crash

sukui — Tue, 02 May 2023 07:05:45 GMT

When I query impala like "select count(1) from t", the impala daemon is correct。but when I change query "select count(distinct(xxx)) from t", the impala daemon unexpected exit.

Error Log:

llvm-codegen.cc:137] dc448ef835296647:2da12cb500000001] LLVM hit fatal error: Cannot select: intrinsic %llvm.x86.sse42.crc32.32.32

Hi @sukui

Can you add following --llvm_cpu_attr_whitelist to Impala Daemon Command Line Argument Advanced Configuration Snippet (Safety Valve).

--llvm_cpu_attr_whitelist=adx,aes,avx,avx2,bmi,bmi2,cmov,cx16,f16c,fma,fsgsbase,hle,invpcid,lzcnt,mmx,movbe,pclmul,popcnt,prfchw,rdrnd,rdseed,rtm,smap,sse,sse2,sse3,sse4.1,ssse3,xsave,xsaveopt

Restart impala and see if it helps.

Regards,
