---------------------------------------

             Summary: Hadoop: Improve Hadoop JAR search logic.
                 Key: IGNITE-3185
                 URL: https://issues.apache.org/jira/browse/IGNITE-3185
             Project: Ignite
          Issue Type: Bug
          Components: hadoop
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
            Assignee: Ivan Veselovsky
             Fix For: 1.7


*Problem*
Currently our {{HadoopClassLoader}} is trying to find common/hdfs/mapred JARs automatically if {{HADOOP_HOME}} is set. However, it checks only for standard Apache Hadoop distribution paths (/share/hadoop/*). For other distributions (CDH, HDP), user has to bother with additional env variables manually.

*Solution*
Try to search for the following folders as well:
$HADOOP_HOME/hadoop
$HADOOP_HOME/hadoop-hdfs
$HADOOP_HOME/hadoop-mapreduce

If all these folders are found, then this is either HDP or CDH deployment and we can create the classpath without additional env vars.
