Subject Re: Problem initializing pipes in HamaStreaming
Date Thu, 26 Sep 2013 14:03:02 GMT
Hi again,

I have updated both Hama (from the trunk) and Streaming (from Martin's
github), and checked that patches have been applied, but I keep
getting the same error (full log for local configuration is attached).

Another thing may be relevant: I keep the default Hadoop libraries in
lib/. If I replace them as the tutorial says, some classes cannot be
found even if  I run pure Hama (which works perfectly with default
libs). I don't know if it is important.

Thanks,
Roman
