I don't have hdfs and want to run on local filesystem storage，any help ??

Hi! Thanks for reporting this.

The issue is that our HDFS integration is enabled in the default build (we should probably change that), and the HDFS client is trying to connect to a local HDFS NameNode (as you guessed).

You can get rid of it by passing -DENABLE_HDFS=off to the cmake invocation that you use to set up your build tree.

I guess we should add a flag that allows you to turn off HDFS support at runtime, and recover more gracefully from this error :)

Thanks for your quick reply！ I will give it a test tomorrow

May the force be with you
