1,报错如下：

ava.lang.RuntimeException: Error when launching multilang subprocessCaused by: java.io.IOException: Cannot run program "python" (in directory "/tmp/eaf0b6b3-67c1-4f89-b3d8-23edada49b04/supervisor/stormdist/word-count-1-1414559082/resources"): error=2, No such file or directory

修复：1，在Eclipse中配置python路径

2，将：multilang目录加入classpath

2,报错如下：

9688 [Thread-34] INFO  backtype.storm.task.ShellBolt - ShellLog pid:11612, name:split Traceback (most recent call last):  File "C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\bc681c09-ff50-4ec3-808f-158917b93992\supervisor\stormdist\word-count-1-1421735162\resources\storm.py", line 172, in run    self.process(tup)  File "splitsentence.py", line 5, in process    words = tup.values[0].split(" ")IndexError: list index out of range

修改splitsentence.py即可

import stormclass SplitSentenceBolt(storm.BasicBolt):    def process(self, tup):        if len(tup.values) != 0:                words = tup.values[0].split(" ")                if len(words) != 0:                    for word in words:                      storm.emit([word])SplitSentenceBolt().run()
