[jira] [Created] (HDFS-9679) libhdfs++: Implement hdfsSeek and hdfsTell that return 64 bit types

-------------------------------------

             Summary: libhdfs++: Implement hdfsSeek and hdfsTell that return 64 bit types
                 Key: HDFS-9679
                 URL: https://issues.apache.org/jira/browse/HDFS-9679
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: James Clampffer
            Assignee: James Clampffer


hdfsSeek and hdfsTell in the libhdfs API return int while libhdfs++ uses int64_t internally.  When seeking to the end of very large files the 64->32 bit narrowing operation done by the bindings gives offset mod 2^32 rather than the offset.

hdfsSeek64 and hdfsTell64 need to be added to the extended C API to avoid these issues.
