APT_IOMGR_CONNECT_ATTEMPTS

Set the APT_IOMGR_CONNECT_ATTEMPTS environment variable to specify the number of attempts for a TCP connect in case of a connection failure.

Setting APT_IOMGR_CONNECT_ATTEMPTS is necessary only for jobs with a high degree of parallelism in an MPP environment. The default value is 2 attempts, that is 1 retry after an initial failure.
