li xiang commented on FLUME-1920:
---------------------------------
According to the comments left by the originator in
flume-ng-tests/src/test/java/org/apache/flume/test/agent/TestFileChannel.java
for findHadoopJar():
* We search the class path of the current JVM process to grab the same
* hadoop jar that's depended on by the file channel.
It seems at that time, file channel depended on hadoop jar.
> Test case TestFileChannel fails when flume is built from paths containing the
> string "hadoop"

> When flume is built from a path that contains the string "hadoop" (ie:
> /home/user/hadoop_components/flume), the test case TestFileChannel fails.
> The reason it fails is because it can't find the correct location of the
> hadoop jar file - the function findHadoopJar in TestFileChannel.java
> looks for the hadoop jar path by searching for the string "hadoop" in the
> property java.class.path, and returns the first match of the search.
> This is not necessarily the correct location of the hadoop jar.
> The right thing to do is to look for the name of the hadoop jar in the
> classpath (ie: hadoop-core-1.1.1.jar), instead of looking for the string
> "hadoop".
