[jira] [Commented] (HADOOP-16929) ARM Compile Scripts only work for
AArch64, not AArch32
[ https://issues.apache.org/jira/browse/HADOOP-16929?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17063265#comment-17063265 ]
Maximilian Böther commented on HADOOP-16929:
--------------------------------------------
Added the fixes as a PR on Github.
Btw, even with the setup for AArch64 (or the fixes for AArch32), one still needs to do some manual tinkering in the build process. E.g. some components like the YARN Application Catalog just blindly download x86 versions of node and thus, the build fails. Also, the known primitive.h issue (see HADOOP-15505) and the soft/hard float issue (see HADOOP-9320) have to be tackled manually. I did a write-down of what is necessary to really compile Hadoop on ARM, but it's just for the native files as I was interested in them. For a full build without e.g. disabling building the application catalog, external fixes have to be applied (see [https://github.com/eirslett/frontend-maven-plugin/issues/884] for example).

> The dockerfile added in HADOOP-16797 only works for AArch32. The detection itself only recognizes 64-bit ARM architectures as well.
