             Summary: Memory leak due to ChunkInputStream.close() not releasing buffer
                 Key: HDDS-7136
                 URL: https://issues.apache.org/jira/browse/HDDS-7136
             Project: Apache Ozone
          Issue Type: Bug
            Reporter: Wei-Chiu Chuang


We found Impala queries that run on ofs does not release memory after complete.

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).
