In fact, Q-Job and Bt-Job have identical input ( of the A matrix) and identical setup of such input but for some reason Bt-job fails to see it. And it fails to see it in a very strange way. That's what perplexing.
Bt job uses output of Q-job as a side info, not as main input. But the error (split error ) comes from the main input which should be A. -d On Thu, Apr 5, 2012 at 12:00 PM, Peyman Mohajerian <mohaj...@gmail.com> wrote: > Ok, great, I'll give these ideas a try later today, the input is the > following line(s) that in my code sample was commented out using ';' in > Clojure. > The first stage, Q-job is done fine, it is the second job that gets messed > up, the output of Q-job is at: > /lsa4solr/matrix/14099700861483/transpose-213/SSVD-out/Q-job and > /lsa4solr/matrix/14099700861483/transpose-213/SSVD-out/Q-job but BtJob is > looking for the input in the wrong place, it must be hadoop version as you > said. > > input path #<Path > hdfs://localhost:9000/lsa4solr/matrix/15835804941333/transpose-120> > dd #<Path[] [Lorg.apache.hadoop.fs.Path;@5563d208> > numCol 1000 > numrow 15982 > > > On Thu, Apr 5, 2012 at 11:54 AM, Dmitriy Lyubimov <dlie...@gmail.com> wrote: > >> Another idea i have is to try to run it from just Mahout command line, >> see if it works with .205.
