> I recently compiled the C++ client (on windows) from master and tested
> against a 1.9.0 drillbit. The client's behavior does not meet the stable
> release requirement.
> Some API functionalities are broken and should be investigated.
> Most noticeable is the getColumns(...) call. It will throw an exception with
> "Cannot decode getcolumns results" when the number of rows (column records)
> exceeds a certain number.
> I also noticed that: during query execution + data retrieval, if the table is
> large enough, the result coming back will start to become NULL or empty.
> I will see if I can generate some drillclient logs to put in the attachment.
> I will also compile and test on other platforms.
