我在requirements.txt文件中写了MySQLdb的库MySQL-python，并且拓扑能够被顺利的build生成jar包，但是当我把jar
包提交以后，出现如下错误信息：
11814 [Thread-12-result-count] ERROR backtype.storm.daemon.executor -
java.lang.RuntimeException: Error when launching multilang subprocess
Traceback (most recent call last):

import MySQLdb
ImportError: No module named MySQLdb
我的yaml文件配置如下：
name: association-miner
topology:
- spout:
name: trans-spout
module: association-miner.spout
- bolt:
name: mining
module: association-miner.mining
parallelism_hint: 3
groupings:
- shuffle_grouping: trans-spout
- bolt:
name: result-count
module: association-miner.result
groupings:
- global_grouping: mining
问题已解决除了在requirements.txt中写‘MySQL-python’，在集群各个节点上也要安装MySQL-python
