[jira] [Commented] (HADOOP-12926) lz4.c does not detect 64-bit mode properly

    [ https://issues.apache.org/jira/browse/HADOOP-12926?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15195398#comment-15195398 ]

----------------------------------------

Hi [~alanburlison].

The LZ4 code in the Hadoop tree is an import from the LZ4 project, and we try to keep it in sync with a known upstream version.  Have you tried reporting this against the LZ4 project?

https://github.com/Cyan4973/lz4

Ideally, it would be fixed there, and we could resolve the Hadoop issue simply by importing a new fixed version of the source.

> lz4.c should check to see if the _LP64 macro is defined to correctly detect when it is being built in 64-bit mode.
