Summary: libhdfs++: Improve parsing of config file entries
Key: HDFS-10634
URL: https://issues.apache.org/jira/browse/HDFS-10634
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: James Clampffer
Assignee: James Clampffer
Config files just specify an authority rather than a real URI for namenodes,
but we've been using the URI class to parse them. This is kind of hacky
because a scheme needs to be prepended (and then ignored) for the library to
work.
The URI parsing library generates errors in valgrind when it doesn't get a
scheme which could be concerning (conditional jump on undefined). At the
moment it's unclear if this is a real issue or it's just using vectorized
string operations that read whole words but the string ends in the middle of a
machine word.
This is also a good place to refactor the split function in uri.h to be general
purpose, right now it has a special rule to disregard leading '/' chars.
