Re: What is 'Read Reuqests' on OpsCenter exaclty?

You're quite right. I missed important thing first. I found a mistake in my program while making test case. It turns out that the original program has 3~4 selects for non-existing row keys plus a select for existing row key. It was intended to do nothing but for next tests. My original test count

I can see two numbers matches when the redundant selects are removed with 1 node/1 replica settings. On 24 April 2015 at 19:09, Bongseo Jang wrote: > You're quite right. I missed important thing first. > > I found a mistake in my program while making test case. It turns out that > the original p

Confirming Repairs

The short answer is I used a logstash query to get a list of all repair ranges started and all ranges completed. I then matched the UUID of the start message to the end message and printed out all the ranges that didn't succeed. Then one needs to go a step further than I've coded and match the rema

Re: Confirming Repairs
