------------------------------------
Summary: [JS] Error reading dictionary-encoded integration test
files
Key: ARROW-1693
URL: https://issues.apache.org/jira/browse/ARROW-1693
Project: Apache Arrow
Issue Type: Bug
Components: JavaScript
Reporter: Brian Hulette
Attachments: dictionary-cpp.arrow, dictionary-java.arrow,
dictionary.json
The JS implementation crashes when reading the dictionary test case from the
integration tests.
To replicate, first generate the test files with java and cpp impls:
{code}
$ cd ${ARROW_HOME}/integration/
$ python -c 'from integration_test import generate_dictionary_case;
generate_dictionary_case().write("dictionary.json")'
$ ../cpp/debug/debug/json-integration-test --integration --json=dictionary.json
--arrow=dictionary-cpp.arrow --mode=JSON_TO_ARROW
$ java -cp
../java/tools/target/arrow-tools-0.8.0-SNAPSHOT-jar-with-dependencies.jar
org.apache.arrow.tools.Integration -c JSON_TO_ARROW -a dictionary-java.arrow -j
dictionary.json
{code}
Attempt to read the files with the JS impl:
{code}
$ cd ${ARROW_HOME}/js/
$ ./bin/arrow2csv.js -s dict1_0 -f ../integration/dictionary-{java,cpp}.arrow
{code}
Both files result in an error for me on
[a8f51858|https://github.com/apache/arrow/commit/a8f518588fda471b2e3cc8e0f0064e7c4bb99899]:
{{TypeError: Cannot read property 'buffer' of undefined}}
