Hi Lars, I used the tarballs from the distributions. I did not build them myself.
I directly used http://people.apache.org/~larsh/hbase-0.94.7-rc0/hbase-0.94.7.tar.gz and http://apache.mirror.rafal.ca/hbase/hbase-0.94.6.1/hbase-0.94.6.1.tar.gz I used them without any modification. I simply exported the JAVA_HOME variable, started HBase and ran the PE application. I tried with more lines (128M instead of 1M) but it failed on timeout (most probably because of GC). I will retry today with only 2M and increase slowly to see if I see any difference. JM 2013/4/20 lars hofhansl <[email protected]>: > I checked with a profile.
