Subject [jira] [Commented] (HBASE-7971) bin/hbase provides incorrect instructions to produce target/cached_classpath.txt
Date Fri, 01 Mar 2013 20:13:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7971?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590899#comment-13590899

Nick Dimiduk commented on HBASE-7971:
-------------------------------------

You guys appear to have necessary magic such that compiling against hadoop-1 does not build
the hadoop-2 compat jar and vice versa. So, I think creation of this file can be moved back
to the compile phase.

However, the new structure is such that the top-level hbase project shows up last in the reactor
list. That means `mvn clean compile` will command hbase-it module to generate the file in
the correct place and then command hbase module to delete it. I propose we keep the cached_classpath
file in hbase-it/target and update bin/hbase to look there.

> The usual workflow of {{mvn clean compile}} followed by {{./bin/hbase foo}} no longer
works. It looks like it was broken by HBASE-7637, switching the phase in hbase-it/pom.xml
from {{compile}} to {{test}}. Before I propose the obvious patch, a couple questions:
> [~nkeywal]: why is this done in hbase-it instead of anywhere else, such as the top-level
pom?
> [~eclark]: why does this execution in the compile phase break hadoop-2 profile while
running it in test does not?
