> We found Impala queries that run on ofs does not release memory after completion.
> Looking at heap dump, we realized unbuffer() was not called (due to HDDS-7135) and Impala calls close() on the input stream instead.

> bq. "Closes this input stream and releases any system resources associated with the stream."
> I believe close() should release buffer in addition to sockets (which it already does).
