(Updated Feb. 25, 2015, 1:27 a.m.) Review request for mesos, Adam B, Benjamin Hindman, Till Toenshoff, and Timothy Chen. Changes ------- Testing return status from fetcher on failure, other minor issue fixes. Bugs: MESOS-2390 https://issues.apache.org/jira/browse/MESOS-2390 Repository: mesos Description ------- Now the containerizer/fetcher sets the HADOOP_HOME variable for mesos-fetcher again if the slave flag hadoop_home is set. Added a test that checks that HDFS fetching is not broken and also ensures that the flag gets translated to the environment variable and then gets applied in mesos-fetcher. Created a mock hadoop implementation script for this. This script has the exact same side effects as a real haddop client in the scope of our testing. Using this, Mesos testing has no extra external dependencies (on Hadoop). Slave flag frameworks_home does not need to be an evironment variable. It is now part of FetcherInfo only, but it also gets tested now that it works.
