Mike Brown (comScore CTO):
We could capitalize the purchase [of MapR] with an annual maintenance charge versus a yearly cost per node. NFS allowed our enterprise systems to easily access the data in the cluster.
Some interesting bits:
- comScore runs a 1000+ self-hosted Hadoop cluster
- comScore migrated from Cloudera to MapR in 2 days
- the migration was accomplished by copying and reloading data
- depending on the size of stored data, a better approach would a rolling migration—
- comScore MapR’s Direct Access NFS feature, which exposes Hadoop Distributed File System (HDFS) data as NFS files which can then be easily mounted, modified or overwritten
- comScore will continue to use Cloudera for training purposes
- Question: what is the advantage of paying two providers and maintaining two different clusters?
As previewed by Cloudera-Hortonworks exchanges, the competition on the Hadoop market is becoming fierce. But at least this story involves companies that are actively involved in innovating and improving Hadoop. Not those that just want to monetize it.
