Colin Patrick McCabe commented on HDFS-7838:
--------------------------------------------
The libhdfs part looks correct, but you didn't add a stub function to
libwebhdfs which returns {{ENOTSUP}} like I asked.
I understand that you are planning on adding full support in libwebhdfs in a
follow-on jira, but it would be better to have the function introduced there in
this JIRA, so that people would not get linker failures when trying to link a
binary using {{hdfsTruncate}} against {{libwebhdfs}}. {{libwebhdfs}} must
implement every function in {{hdfs.h}}.
