Chris Nauroth commented on HDFS-8346:
-------------------------------------
* HDFS-573 implemented Windows compatibility for libhdfs. As part of this
effort, we refactored OS-specific system calls into OS-specific source files.
We also introduced htable.c for a platform-neutral hash table implementation.
libwebhdfs includes jni_helper.c from libhdfs in its own build. jni_helper.c
depends on the OS-specific sources and the hash table, but since the libwebhdfs
build was not updated to include these files, this causes unresolved external
symbols.
* HADOOP-11403 introduced the {{terror}} function in exception.c as a
cross-platform thread-safe error reporting function. libwebhdfs code was
changed to call this function, but libwebhdfs doesn't use the exception.c from
hadoop-common. Instead, it uses the exception.c from libhdfs, which does not
have this function.
> libwebhdfs build fails during link due to unresolved external symbols.
