-------------------------------------
Summary: Memory leak issue in Zlib compressor
Key: HADOOP-14392
URL: https://issues.apache.org/jira/browse/HADOOP-14392
Project: Hadoop Common
Issue Type: Bug
Components: common
Affects Versions: 3.0.0-alpha2, 3.0.0-alpha1, 2.6.0
Reporter: Jimmy Ouyang
Priority: Critical
While using Hadoop-2.6.0 and Hadoop-3.0, we noticed in
hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/io/compress/CompressorStream.java,
there is memory leak due to missing calls to compressor.end() in function
close(). compressor.end() function calls zlib native function deflateEnd(), in
which zlib buffers are freed.
