Hello,
We plan to install a federated Hadoop Cluster to host several internal applications that have specifics needs. While this topics is poorly documented, we discover that the FS need to be formated after the hadoop cluster is configured with at least two Name Space during the Setup.
The first question is why the FS should be formatted when deploying two Name Spaces, perhaps regarding the blockpool parameters ? And the second is what about adding a third Name Space in Production, do we’ll have to format the FS (i hope not) or Hadoop can handle a newly added FS without doing such an operation ?
Thanks in advance for your tips or advice, and best regards,
Emmanuel
