我想你是在用这样的东西连接到 impala 通过 impyla ... 尝试执行 invalidate metadata <table_name> 命令

from impala.dbapi import connect
conn = connect(host='my.host.com', port=21050)
cursor = conn.cursor()
cursor.execute('INVALIDATE METADATA mytable') # run this
cursor.execute('SELECT * FROM mytable LIMIT 100')
print cursor.description  # prints the result set's schema
results = cursor.fetchall()
