-----------------------------------------
Summary: NFS Gateway may release buffer too early
Key: HADOOP-18569
URL: https://issues.apache.org/jira/browse/HADOOP-18569
Project: Hadoop Common
Issue Type: Bug
Components: nfs
Affects Versions: 3.4.0, 3.3.5, 3.2.5, 3.3.9
Reporter: Attila Doroszlai
Assignee: Attila Doroszlai
After upgrading Netty from 4.1.68 to 4.1.77 (HADOOP-18079), NFS Gateway started
crashing when writing data (can be easily reproduced by a few 10MB+ files).
The problem was triggered by [reduced default chunk size in
PooledByteBufAllocator|https://github.com/netty/netty/commit/f650303911] (in
4.1.75), but it turned out to be caused by a buffer released too early in NFS
Gateway.
