Change subject: IMPALA-15214: [DOCS] Update CPU requirements ...................................................................... IMPALA-15214: [DOCS] Update CPU requirements The requirements page still listed SSSE3, but since IMPALA-9690 (Impala 4.0) the daemons refuse to start on x86-64 CPUs without AVX2, unless the deprecated --enable_legacy_avx_support flag relaxes this to AVX. The CPU requirement moves out of "Hardware Requirements for Optimal Join Performance" into a new "CPU Requirements" section, since it is a hard requirement, not a performance recommendation. It now covers AVX2 and the legacy AVX mode on x86-64, the ARMv8-A + CRC32 requirement on ARM64 (IMPALA-15369), and how to check a machine. The 4.0.x incompatible changes section lists the AVX2 requirement too, because the external 4.0 release notes mention only AVX. Testing: - Built the HTML docs with DITA-OT and checked the rendered pages.
