Subject Hadoop 3.0.0-alpha2 startup issue
Date Thu, 23 Feb 2017 20:31:09 GMT
Hi !

I have a lab system running ok with alpha1 and I wanted to switch to alpha2. Unfortunately
I run into issue trying to bring up HDFS, even after reformatting it. I keep getting this
type of error in the HDFS daemon logs:
2017-02-22 15:05:45,577 ERROR namenode.NameNode (NameNode.java:main(1709)) - Failed to start

Wondering if you have seen similar errors or how to fix it. I made sure all my settings point
to alpha2 install

Have a nice day,
Dani
