Load user library to Hama

Hi,

I am new to Hama and got a question for using it.

I am writing my own VertexInputReader and need a third party library to parse the input. How should I ship the library jar to the GroomServer in Hama. I have tried to use the –libjars option but did not work: got ClassNotFoundException in the VertexInputReader part.


Thanks a lot

Min

Hi Tu, Min

You can solve the problem by copying your 3rd party library to
{$HAMA}/lib folder.

Hi,

Can you give us the command you are trying. Also, you can try the
distributed cache feature of Hadoop for the same.

Thanks,
Suraj
