James Clampffer updated HDFS-9679:
----------------------------------
Description: It'd be nice to have a version of hdfsSeek that returns the
new offset as a 64 bit int similar to a posix lseek. The underlying C++
implementation already does this for free and doing a seek with whence=SEEK_CUR
and then checking the resulting offset seems like a common operation. (was:
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.)
