Subject [jira] [Commented] (HADOOP-14842) Hadoop 2.8.2 release build process get stuck due to java issue
Date Thu, 07 Sep 2017 21:36:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14842?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16157711#comment-16157711

Junping Du commented on HADOOP-14842:
-------------------------------------

I tried to apply HADOOP-14816 but hitting with many conflicts -almost all for Dockerfile.
Sounds like we are missing many patches in branch-2 and 2.8. Do we need to backport all/most
of them back to branch-2/2.8? I saw we were upgrading cmake, maven, etc. Some patch like remove
JDK 7 should definitely be ignored. Will backport rest of them can cause incompatible issues?
If backport is a risky option, It would be nice if we can have a fix for branch-2/branch-2.8
only.

> In my latest 2.8.2 release build (via docker) get failed, and following errors received:
>  
> {noformat}
> "/usr/bin/mvn -Dmaven.repo.local=/maven -pl hadoop-maven-plugins -am clean install
> Error: JAVA_HOME is not defined correctly. We cannot execute /usr/lib/jvm/java-7-oracle/bin/java"
> {noformat}
> This looks like related to HADOOP-14474. However, reverting that patch doesn't work here
because build progress will get failed earlier in java download/installation - may be as mentioned
in HADOOP-14474, some java 7 download address get changed by Oracle. 
> Hard coding my local JAVA_HOME to create-release or Dockerfile doesn't work here although
it show correct java home. My suspect so far is we still need to download java 7 from somewhere
to make build progress continue in docker building process, but haven't got clue to go through
this.
