Subject BloomFilter error: stream is closed
Date Thu, 21 Dec 2017 15:34:23 GMT
Hi

We've activated the bloomfilter on an accumulo table to see if it
helped with the CPU usage and we're seeing this messages in our
tserver debug log:

Does anyone know what these mean or what is causing them?

Thank you.
