Re: Exceptions not caught?

[Ted Yu]

Can you show the stack trace ?

Also, how do you catch exceptions ? Did you specify TProtocolException ?

Cheers

 Hi, I'm running a spark job and encountering an exception related to
 thrift.
 I wanted to know where this is being thrown, but the stack trace is
 completely useless. So I started adding try catches, to the point where my
 whole main method that does everything is surrounded with a try catch. Even
 then, nothing is being caught. I still see this message though:

 2014-10-23 15:39:50,845  ERROR [] Exception in task 1.0 in stage 1.0 (TID
 1)
 java.io.IOException: org.apache.thrift.protocol.TProtocolException:
 .

 What is going on? Why isn't the exception just being handled by the
 try-catch? (BTW this is in Scala)

Also everything is running locally on my box, driver and workers.

[ankits]

Can you check your class Y and fix the above ?

I can, but this is about catching the exception should it be thrown by any
class in the spark job. Why is the exception not being caught?

This looks like an exception that's happening on an executor and just
being reported in the driver's logs, so there's nothing to catch in
the driver, which might explain why you're not catching anything.
