I'm trying to import around 6M nodes using Michael Hunger's batch importer but I'm getting this weird error:
java.lang.NumberFormatException: For input string: "78rftark42lp5f8nadc63l62r3" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
It is weird because 78rftark42lp5f8nadc63l62r3 is the very first value of the big CSV file that I'm trying to import and its datatype is set to string.
These are the first three lines of that file:
name:string:sessions labels:label timestamp:long:timestamps visitor_pid referrer_url 78rftark42lp5f8nadc63l62r3 Session 1401277353000 cd7b76ef09b498e95b35b49de2925c5f http://someurl.com/blah?t=123 dt2gshq5pao8fg7bka8fdri123 Session 1401277329000 4036ac507698e4daf2ada98664da6d58 http://enter.url.com/signup/signup.php
As you can see here name:string:session the datatype of that column is set to string, why is the importer trying to parse the value as long?
I'm completely new to Neo4j and its ecosystem so I'm sure I'm missing something here.
This is the command I ran to import a bunch of nodes and relations:
./import.sh \
-db-directory sessions.db \
-nodes "toImport/browser-nodes.csv.gz,toImport/country-nodes.csv.gz,toImport/device-nodes.csv.gz,toImport/ip-nodes.csv.gz,toImport/language-nodes.csv.gz,toImport/operatingSystem-nodes.csv.gz,toImport/referrerType-nodes.csv.gz,toImport/resolution-nodes.csv.gz,toImport/session-nodes.csv" \
-rels "toImport/rel-session-browser.csv.gz,toImport/rel-session-country.csv.gz,toImport/rel-session-device.csv.gz,toImport/rel-session-ip.csv.gz,toImport/rel-session-language.csv.gz,toImport/rel-session-operatingSystem.csv.gz,toImport/rel-session-referrerType.csv.gz,toImport/rel-session-resolution.csv.gz"
The file that fails is the last one in the list of nodes toImport/session-nodes.csv
The other files were successfully processed by the importer.
This is the content of the batch.properties file:
dump_configuration=false
cache_type=none
use_memory_mapped_buffers=true
neostore.propertystore.db.index.keys.mapped_memory=1G
neostore.propertystore.db.index.mapped_memory=3G

batch_import.node_index.countries=exact
batch_import.node_index.languages=exact
batch_import.node_index.ips=exact

Any thoughts? I can't see what's the problem here so any help will be appreciated.
