## Extraction Task
-TODO:
+An example actually connecting to HBase from a local machine, with thrift
+running on a devbox and GROBID running on a dedicated machine:
+
+ ./extraction_cdx_grobid.py \
+ --hbase-table wbgrp-journal-extract-0-qa \
+ --hbase-host bnewbold-dev.us.archive.org \
+ --grobid-uri http://wbgrp-svc096.us.archive.org:8070
+ tests/files/example.cdx
## Backfill Task
An example actually connecting to HBase from a local machine, with thrift
running on a devbox:
- ./backfill_hbase_from_cdx.py tests/files/example.cdx \
+ ./backfill_hbase_from_cdx.py \
--hbase-table wbgrp-journal-extract-0-qa \
--hbase-host bnewbold-dev.us.archive.org
+ tests/files/example.cdx
Actual invocation to run on Hadoop cluster (running on an IA devbox, where
hadoop environment is configured):
# Create tarball of virtualenv
pipenv shell
- tar -czf backfill-4OmRI0zZ.tar.gz -C /home/bnewbold/.local/share/virtualenvs/backfill-4OmRI0zZ .
+ export VENVSHORT=`basename $VIRTUAL_ENV`
+ tar -czf $VENVSHORT.tar.gz -C /home/bnewbold/.local/share/virtualenvs/$VENVSHORT .
./backfill_hbase_from_cdx.py \
- -r hadoop \
