Creating vertica database on HDFS + NFS failed
Setup -
HDFS + NFS :
Take a 3 node Hadoop cluster.
Export the HDFS filesystem using the Hadoop NFS gateway.
The HDFS filesystem is now accesible as a NFS export.
Vertica :
Install vertica on 2 nodes. ( Community License )
Mount the HDFS + NFS exported filesystem on one vertica node.
mount -t nfs -o nolock hserver:/ /mnt/vert1
Create a vertica database with 1 node only, and specify catalog and data directories in mounted path -
/mnt/vert1/vertica/c3, /mnt/vert1/vertica/d3
Database creation fails with an error -
Unable to bootstrap database: License installed for Vertica Community Edition
I tried the same experiment with a normal NFS exported filesystem, and there were no problems while creating the database.
The vertica documentation says -
Community Edition licenses cannot be installed co-located in a Hadoop infrastructure and used to query data stored in Hadoop formats.
But is there really anyway for vertica to figure out the actual filesystem behind NFS ?
The HDFS filesystem has terabytes of free space.
What could be the problem ?
