Hi, I have successfully installed scipy on my Python 2.7 on my local Linux, and I want to pack my Python2.7 (with scipy) onto Hadoop and run my Python MapReduce scripts, like this:
20 ${HADOOP_HOME}/bin/hadoop streaming \$ 21 -input "${input}" \$ 22 -output "${output}" \$ 23 -mapper "python27/bin/python27.sh rp_extractMap.py" \$ 24 -reducer "python27/bin/python27.sh rp_extractReduce.py" \$ 25 -partitioner org.apache.hadoop.mapred.lib.KeyFieldBasedPartitioner \$ 26 -file rp_extractMap.py \$ 27 -file rp_extractReduce.py \$ 28 -file shitu_conf.py \$ 29 -cacheArchive "/share/python27.tar.gz#python27" \$ 30 -outputformat org.apache.hadoop.mapred.TextOutputFormat \$ 31 -inputformat org.apache.hadoop.mapred.CombineTextInputFormat \$ 32 -jobconf mapred.max.split.size="512000000" \$ 33 -jobconf mapred.job.name="[reserve_price][rp_extract]" \$ 34 -jobconf mapred.job.priority=HIGH \$ 35 -jobconf mapred.job.map.capacity=1000 \$ 36 -jobconf mapred.job.reduce.capacity=200 \$ 37 -jobconf mapred.reduce.tasks=200$ 38 -jobconf num.key.fields.for.partition=2$ I have to do this, because the Hadoop server installed its own python of very low version which may not support some of my python scripts, and I do not have privilege to install scipy lib on that server. So,I have to use the -cacheArchieve command to include my own python2.7 with scipy.... But, I find out that some of the .so in scipy are linked to other dynamic libs outside Python2.7.. For example $ ldd ~/local/python-2.7.2/lib/python2.7/site-packages/scipy/linalg/flapack.so liblapack.so => /usr/local/atlas/lib/liblapack.so (0x0000002a956fd000) libatlas.so => /usr/local/atlas/lib/libatlas.so (0x0000002a95df3000) libgfortran.so.3 => /home/work/local/gcc-4.6.1/lib64/libgfortran.so.3 (0x0000002a9668d000) libm.so.6 => /lib64/tls/libm.so.6 (0x0000002a968b6000) libgcc_s.so.1 => /home/work/local/gcc-4.6.1/lib64/libgcc_s.so.1 (0x0000002a96a3c000) libquadmath.so.0 => /home/work/local/gcc-4.6.1/lib64/libquadmath.so.0 (0x0000002a96b51000) libc.so.6 => /lib64/tls/libc.so.6 (0x0000002a96c87000) libpthread.so.0 => /lib64/tls/libpthread.so.0 (0x0000002a96ebb000) /lib64/ld-linux-x86-64.so.2 (0x000000552aaaa000) So, my question is: how can I include this libs? Should I search for all the linked .so and .a under my local linux and pack them together with Python2.7??? If yes, How can I get a full list of the libs needed and How can make the packed Python2.7 know where to find the new libs?? Thanks Xiong
