impalad stability, and I find when I run ten thousand times, the following
error will occur two times in impalad.INFO log file.

import impala.dbapi
test_conf = {
'host': '172.16.24.xx',
'port': 21050,
'user': 'xxxx',
'password': 'xxxxx'
}
def test_impala(conf):

conn.close()
N = 10000
for i in range(N):
test_impala(test_conf)
```
