Subject [jira] Commented: (HADOOP-3264) libhdfs does not provide permissions in API
Date Sun, 13 Jul 2008 13:07:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12613162#action_12613162

Craig Macdonald commented on HADOOP-3264:

I'm not particularly opinionated on either options. Could we rely on .so versioning to flag
incompatible API changes? I cant really comment on the versioning of C APIs.

The current implemented methods in libhdfs that are related are
hdfsFileInfo *hdfsGetPathInfo(hdfsFS fs, const char* path);
char*** hdfsGetHosts(hdfsFS fs, const char* path, 
            tOffset start, tOffset length);
int hdfsSetReplication(hdfsFS fs, const char* path, int16_t replication);
so in a sense, we have both kinds of methods going on here.

Arun is the original libhdfs contributor, so perhaps he can comment on a preferred API style?
