[jira] [Commented] (HADOOP-11426) Fix native bzip2 codec build dependency

    [ https://issues.apache.org/jira/browse/HADOOP-11426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14534592#comment-14534592 ] 

Kihwal Lee commented on HADOOP-11426:
-------------------------------------

There is no rule for build_env == runtime_env, but I agree that is atypical in hadoop. Won't fix.

> In hadoop-common-project/hadoop-common/src/CMakeLists.txt, find_package() is used to check whether bzip2 libraries and header are present.  However, the library is loaded by libhadoop using dlopen(), not linked during build, so the real build-time dependency is only on the header file.
