Subject Re: [VOTE] The 1st HBase 0.98.22 release candidate (RC0) is available
Date Mon, 05 Sep 2016 05:41:57 GMT
Ugh, sorry guys, I'm dumb. I was running 1 mapper per RS before, but
switched to a d2.4xlarge instance today and, after noticing cores sitting
idly, decided to try setting the number of mappers and reducers to the
number of cores to speed testing up (RAM is still grossly underutilized
with less than 16 GB/122 GB in use at any one time). This definitely made
runs go faster (generation took less than 3 hours, verification took about
1 hour), but I just realized that the number of nodes I picked (62500000)
isn't a multiple of 25,000,000 and so the list won't wrap properly. I'll
rerun and confirm, but I'm guessing this is a false alarm.

Sorry again. :(
