Is the existance of this JIRA sufficient documentation until above is fixed?
BuiltIn Gzip compressor decompressor not getting pooled, leading to native
memory leak
Key: HBASE-5881
URL: https://issues.apache.org/jira/browse/HBASE-5881
Project: HBase
Issue Type: Bug
Components: io
Affects Versions: 0.92.1
Reporter: Gopinathan A
Assignee: ramkrishna.s.vasudevan
Priority: Critical
Fix For: 0.92.2, 0.96.0, 0.94.1
This issue will occur only in hadoop 23.x above/
In hadoop 0.20.x
{code}
public static void returnDecompressor(Decompressor decompressor) {
if (decompressor == null) {
return;
}
decompressor.reset();
payback(decompressorPool, decompressor);
}
{code}
In hadoop 0.23.x
{code}
public static void returnDecompressor(Decompressor decompressor) {
if (decompressor == null) {
return;
}
// if the decompressor can't be reused, don't pool it.
if (decompressor.getClass().isAnnotationPresent(DoNotPool.class)) {
return;
}
decompressor.reset();
payback(decompressorPool, decompressor);
}
{code}
Here annotation has been added. By default this library will be loaded if
there are no native library.
{code}
@DoNotPool
public class BuiltInGzipDecompressor
{code}
Due to this each time new compressor/decompressor will be loaded, this leads
to native memory leak.
