found in classpath of parent classloader.
Vladimir Ozerov created IGNITE-3928:
---------------------------------------
Summary: Hadoop: print warning if Hadoop is found in classpath of parent classloader.
Key: IGNITE-3928
URL: https://issues.apache.org/jira/browse/IGNITE-3928
Project: Ignite
Issue Type: Sub-task
Components: hadoop
Affects Versions: 1.7
Reporter: Vladimir Ozerov
Assignee: Ivan Veselovsky
Fix For: 1.8
Normally parent classloader should not have Hadoop in classpath. Otherwise we may end up in JAR hell situation.
We need to probe parent classloader for Hadoop and print a warning if Hadoop is likely to be in the classpath. E.g. we can probe for {{FileSystem}} or {{Configuration}} class.
