---------------------------------
Summary: [Python/C++] Allow passing HDFS Config values via
map/dict instead of needing an hdfs-site.xml file
Key: ARROW-2661
URL: https://issues.apache.org/jira/browse/ARROW-2661
Project: Apache Arrow
Issue Type: New Feature
Components: C++, Python
Affects Versions: 0.10.0
Reporter: Matt Topol
Currently in order to pass HDFS configurations of values down to the underlying
libhdfs driver you have to either set HADOOP_HOME (using libhdfs) or
LIBHDFS3_CONF (for libhdfs3) to point to a location of an hdfs-site.xml file to
use. However the API provided by them allows for calling hdfsBuilderConfSetStr
to set arbitrary configuration values on the hdfsBuilder object. This would
allow for consumers to programmatically set any arbitrary configurations they
want including allowing for encryption and other complex hdfs configurations
without needing to provide an hdfs-site.xml file.
