HAWQ-1782. Fix failed to read EXTERNAL TABLE of GPFDIST protocol - revise CREATE EXTERNAL TABLE default to READABLE EXTERNAL TABLE - fix read from EXTERNAL TABLE of GPFDIST protocol The documented behaviour of CREATE EXTERNAL TABLE indicates a READABLE TABLE but used to be violated. Referring to https://curl.se/libcurl/c/curl_multi_fdset.html, ``` If no file descriptors are set by libcurl, max_fd will contain -1 when this function returns. Otherwise it will contain the highest descriptor number libcurl set. When libcurl returns -1 in max_fd, it is because libcurl currently does something that isn't possible for your application to monitor with a socket and unfortunately you can then not know exactly when the current action is completed using select(). You then need to wait a while before you proceed and call curl_multi_perform anyway. How long to wait? Unless curl_multi_timeout gives you a lower number, we suggest 100 milliseconds or so, but you may want to test it out in your own particular conditions to find a suitable value. ``` it is not an error of `max_fd == -1`. Moreover, the situation of `max_fd == -1` seems common on macOS.
