-------------------------------------
Summary: libhdfs++: Reimplement Status object as a normal struct
Key: HDFS-9712
URL: https://issues.apache.org/jira/browse/HDFS-9712
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: James Clampffer
Assignee: James Clampffer
hdfs::Status is doing all sorts of reinterpret casts on a block of memory
referenced by a char *. Using a char *, casting to a wider type, and
dereferencing can cause fun alignment issues.
As far as I can tell that data layout in status can be boiled down to:
{code}
class Status {
int code;
std::string msg;
}
{code}
This avoids doing manual memcopies in the copy ctor and delete[]s in the dtor.
It will also get rid of boilerplate null checks and casts.
