Subject [jira] [Commented] (CRUNCH-350) Non-serializable BloomFilter field in BloomFilterJoinStrategy should be marked transient
Date Sun, 02 Mar 2014 22:05:21 GMT

Jinal Shah commented on CRUNCH-350:
-----------------------------------

Hey Josh, I actually was trying to write the generalized version of it, while doing so I realized
that I was accidently passing a MemTable and DoTable while joining in the MemPipeline and
there were 2 DoTable passed in the MRPipeline. In that scenario I get the error Saranya was
getting. So I went ahead and confirmed with her and yaah that was the case. I hope that helps
in finding out more about your doubt. I don't know it should throw this exception if both
the tables are of different type. If it should then I think we can check the type of tables
passed before actually trying to join to avoid such exception later.

> Got a notice from the user mailing list that the BloomFilterJoinStrategy was throwing
a NotSerializableException. I took a look at the code and noticed a DoFn field that should
be marked as transient.
