--------------------------------------
Summary: HADOOP_OPTIONAL_TOOLS not parsed correctly
Key: HADOOP-14498
URL: https://issues.apache.org/jira/browse/HADOOP-14498
Project: Hadoop Common
Issue Type: Bug
Components: build
Affects Versions: 3.0.0-alpha1
Reporter: Mingliang Liu
# This will make hadoop-azure not show up in the hadoop classpath, though both
hadoop-aws and hadoop-azure-datalake are in the
classpath.{code:title=hadoop-env.sh}
export HADOOP_OPTIONAL_TOOLS="hadoop-azure,hadoop-aws,hadoop-azure-datalake"
{code}
# And if we put only hadoop-azure and hadoop-aws, both of them are shown in the
classpath.
{code:title=hadoop-env.sh}
export HADOOP_OPTIONAL_TOOLS="hadoop-azure,hadoop-aws"
{code}
This makes me guess that, while parsing the {{HADOOP_OPTIONAL_TOOLS}}, we make
some assumptions that hadoop tool modules have a single "-" in names, and the
_hadoop-azure-datalake_ overrides the _hadoop-azure_. Or any other assumptions
about the {{${project.artifactId\}}}?
