Colin Patrick McCabe commented on HDFS-7014:
--------------------------------------------
Hi Zhanwei, I'm going to assign this one to you since the code is yours
originally.
{code}
+SET(HEADER
+ client/BlockLocation.h
+ client/DirectoryIterator.h
+ client/FileStatus.h
+ client/FileSystem.h
+ client/FileSystemStats.h
+ client/InputStream.h
+ client/OutputStream.h
+ client/Permission.h
+ common/Exception.h
+ common/SharedPtr.h
+ common/XmlConfig.h
+)
{code}
Can we discuss exporting header files in a future JIRA? I think that we will
have to use great care when designing a C\+\+ API. [~wheat9] has already
raised some issues in HDFS-7207, and I think there are a lot more issues to
discuss. The more files we expose, the harder it will be to modify anything in
the future, so I would like to expose as little as possible. So let's discuss
the C\+\+ API in a follow-on JIRA once this stuff is in.
{code}
+ ${R}/hadoop-hdfs-project/hadoop-hdfs/src/main/proto/encryption.proto
+ ${R}/hadoop-hdfs-project/hadoop-hdfs/src/main/proto/inotify.proto
{code}
Thanks for adding these. Too bad we don't support encryption yet :)
{code}
change the interface of InputStream::open to
void open(FileSystem &fs,
const char *path, bool verifyChecksum = true);
{code}
I guess this makes sense since {{FileSystem}} simply contains a {{shared_ptr}}
to a {{FileSystemImpl}} and no other state. We could equally well just copy it.
