Error starting NameNode - Hopsworks 0.9

[arse...@gmail.com]

Hi, 

thanks for the reply on my previous post.

Hopsworks 0.9

There are 2 NameNode. If I start a NameNode and after 10 seconds the second NameNode, the services fail with the error below.

If I start the 2 NameNode together, one of them start correctly. The other fail with the same error below.

Do you understand why?

Thanks,

Hi,

I don't understand why one of the namenode starts and not the other. Can you try to start only one namenode, wait for it to get out of safe mode and then start the second namenode?

Regards,

Gautier

Hi,

I have done it. But after some seconds NameNode fails with the same error. I tired with both NameNode.
