Subject Extremely large ValidationExecutor.MaxPoolSize in Cassandra 2.1.13
Date Thu, 24 Nov 2016 06:20:50 GMT

We are using Cassandra 2.1.13 in a production environment. I was verifying Threadpools.MaxPoolSize
to check for under/over allocated pool counts. 

In our environment ValidationExecutor.MaxPoolSize is 2.147 Billion. Please refer the below

Is this a known issue? Is it safe to ignore? Is there a problem with the allocation or with
the metric calculation itself? Can we fix this with some configuration changes/patches?

Any help is appreciated.
