> Over time, a drillbit tends to hang. Eg. If a drillbit runs out of memory, the drillbit will still be in the list of drillbits returned by zookeeper. Since Drill Client randomly selects a drillbit from that list, the drillbit it connects to may be unhealthy. Drill Client should do a quick connection check to determine whether drillbit is actually healthy. If not, it should select another drillbit and test again until it has found a healthy drillbit.
