Subject [jira] [Commented] (HDFS-10672) libhdfs++: reorder directories in src/main/libhdfspp/examples, and add C++ version of cat tool
Date Fri, 29 Jul 2016 14:12:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15399383#comment-15399383

Anatoli Shein commented on HDFS-10672:
--------------------------------------

Thank you for your commnets, [~bobhansen]. I have fixed the following issues in the new patch:

* The last_bytes_read parameter should be set to sizeof(buf) each time. That makes this a
very messy and error-prone API; buf_size and bytes_read should be different parameters. Let's
fix it as part of this bug.
(/) Done. Now PositionRead takes 4 parameters.

* We should distinguish between normal end-of-file failures to read and "there was an error"
status. What should we expect when we get to EOF? We should document that in the headers.
(/) Done. I created a new error: invalid offset, which is set when trying to begin a read
after the EOF, and documented this in the headers.

> src/main/libhdfspp/examples should be structured like examples/language/utility instead
of examples/utility/language for easier access by different developers.
> Additionally implementing C++ version of cat tool.
