hfind compiles, but exeception thrown on execution

[nagos1]

Hey There Pierre!

Thank you for your hard work on this. We use it quite a bit in our day-to-day hadoop activities. We've recently upgraded from cdh3u3 to cdh4.3.1. I had the exact same issue described in this thread:

#2

After executing the install via override of the hadoop.version parameter, hfind compiles successfully. However, executing hfind after compilation returns this error:

./hfind /user/pierre

Exception in thread "main" java.lang.VerifyError: (class: com/google/common/collect/Interners, method: newWeakInterner signature: ()Lcom/google/common/collect/Interner;) Incompatible argument to function

What am I doing wrong?

Thanks in advance!

Could you try the following patch?

I had the same issue and it worked for me when i removed this com.google.collections dependency.
But then when trying to use hfind I get another error..
Error crawling HDFS: No FileSystem for scheme: hdfs.
not sure if this is somehow related to removing that dependency?

See also #5.

Can you open a separate issue?
