-----------------------------
Summary: HADOOP_HOME no longer works with fetcher
Key: MESOS-2390
URL: https://issues.apache.org/jira/browse/MESOS-2390
Project: Mesos
Issue Type: Bug
Components: fetcher, hadoop
Reporter: Adam B
Assignee: Bernd Mathiske
As of commit "699e638ef80739203ed38ba7238bbc176b107355 Consolidate all fetcher
env vars into one that holds a JSON object." the HADOOP_HOME environment
variable is no longer set when starting the fetcher, which means that
hdfs.hpp's HDFS() will no longer look for the hadoop binary inside the
user-provided HADOOP_HOME, whether it was specified via --hadoop_home or the
HADOOP_HOME env variable.
This is a regression in functionality from Mesos 0.21 and before, and breaks
the use of HDFS when not installed in the slave's PATH. The future fetcher
patch(es) for 0.23+ fixes this, but we need something in 0.22 to prevent
regression.
