Alejandro Abdelnur created HADOOP-8810:
------------------------------------------
Summary: when building with documentation build stops waiting for
ENTER on terminal
Key: HADOOP-8810
URL: https://issues.apache.org/jira/browse/HADOOP-8810
Project: Hadoop Common
Issue Type: Improvement
Components: build
Affects Versions: 2.0.3-alpha
Reporter: Alejandro Abdelnur
Assignee: Alejandro Abdelnur
Fix For: 2.0.3-alpha
When building the docs {{mvn clean package -Pdocs -DskipTests site site:stage
-DstagingDirectory=/tmp/hadoop-site}}, in OSX (and I've seen it a few times in
Ubuntu as well), the build stops, if you press ENTER it continues. It happens
twice.
I've traced this down to the exec-maven-plugin invocation of protoc for
hadoop-yarn-api module (and other YARN module I don't recall at the moment).
jstacking the Maven process it seems the exec-maven-plugin has some locking
issues consuming the STDOUT/STDERR of the process being executed.
I've converted the protoc invocation in the hadoop-yarn-api to use the antrun
plugin instead and then another module running protoc using exec-maven-puglin
hang.
