如果報錯：'TSocket' object has no attribute 'isOpen' 則是thrift-sasl的版本太高了(0.3.0)，故將thrift-sasl的版本降級到0.2.1
pip install thrift-sasl==0.2.1 impyla
報錯：ThriftPy does not support generating module with path in protocol 'c'
主要是源碼在解析url的時候出現錯誤，解決方法如下：
修改windows端中的parser 代碼，筆者代碼位置如下： C:\ProgramData\Anaconda2\Lib\site-packages\thriftpy\parser
修改其中的488行爲如下情況：
#if url_scheme == '':
if len(url_scheme) <= 1:
然後重新運行即可。
報錯：thriftpy.transport.TTransportException: TTransportException(message="Could not start SASL: b'Error in sasl_client_start (-4) SASL(-4): no mechanism available: Unable to find a callback: 2'", type=1)
其中，authMechanism的值取決於hive-site.xml裏的配置
<name>hive.server2.authentication</name>
<value>NOSASL</value>
默認爲NONE，另外還可以爲’NOSASL’, ‘PLAIN’, ‘KERBEROS’, ‘LDAP’.
瞭解導auth_mechanism 這個參數的取值可以是：’NOSASL’, ‘PLAIN’, ‘KERBEROS’, ‘LDAP’.
需要查看hive的配置文件hive-site.xml裏面的取值，於是找到對應文件：
取值爲NONE，修改測試裏的參數：
from impala.dbapi import connect
conn = connect(host='*',port = 10000,auth_mechanism='NONE')
cur=conn.cursor()
cur.execute('SHOW databases;')
print(cur.fetchall())
cur.close()
conn.close()
