>
> 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.
> According to InputStream javadoc, the close() should
> 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).
