[jira] [Created] (HADOOP-9934) the generic (non x86) libhadoop CRC
code makes unaligned loads and stores
Colin Patrick McCabe created HADOOP-9934:
--------------------------------------------
Summary: the generic (non x86) libhadoop CRC code makes unaligned loads and stores
Key: HADOOP-9934
URL: https://issues.apache.org/jira/browse/HADOOP-9934
Project: Hadoop Common
Issue Type: Bug
Components: native
Affects Versions: 2.3.0
Reporter: Colin Patrick McCabe
Priority: Minor
The generic (non-x86) libhadoop CRC code makes unaligned loads and stores. Some architectures don't support unaligned loads and stores, or they are slow. This code should be made truly CPU-neutral by removing unaligned access.
