Hi Suresh, David,
I think I speculated that it *might* be a bug in GeoMesa, but I haven't
seen any evidence of that yet. David, do you still see those warnings
after cleaning up your close methods? In normal operation, I don't see
those, but possibly the access patterns you're using are different.
Suresh, make sure that you're closing any readers you open.
Thanks,
Emilio

Subject: Getting IOExceptions in internalRead!
Hello Everyone,
I am trying to query an accumulo table using geomesa, everything works
fine, I get the correct result of the query but getting warnings
logged about "Error closing output stream". Here is sample log:
[WARN] 2017-05-04 11:57:03 TIOStreamTransport:112 - Error closing
output stream.
java.io.IOException: The stream is closed

I searched regarding the same but found that it's saying something
related to overloading your clusters. How to solve this?
Thank You
