I'm seeing deterministic errors around the Zipfian generation when I need to generate hundreds of millions of random numbers. Here's a sample:
panic: runtime error: index out of range [-2] goroutine 1387 [running]: math/rand.(*rngSource).Uint64(...) /usr/local/go/src/math/rand/rng.go:249 math/rand.(*rngSource).Int63(0xc0000d45a0?) /usr/local/go/src/math/rand/rng.go:234 +0x92 math/rand.(*Rand).Int63(...) /usr/local/go/src/math/rand/rand.go:96 math/rand.(*Rand).Float64(...) /usr/local/go/src/math/rand/rand.go:207 github.com/pingcap/go-ycsb/pkg/generator.(*Zipfian).next(0xc49960f560, 0xc0000e1830, 0x1) /go/pkg/mod/github.com/pingcap/go-ycsb@v1.0.1/pkg/generator/zipfian.go:151 +0x4e github.com/pingcap/go-ycsb/pkg/generator.(*Zipfian).Next(...) /go/pkg/mod/github.com/pingcap/go-ycsb@v1.0.1/pkg/generator/zipfian.go:169
In the next couple of days I'll isolate this and reply back but wanted to have this placeholder to keep track of this issue.
