Hi Sushant,

We apologies for the delay in response. Yes, block size remains same as 128 mb across all the nodes where ever it is copied.

Hi,

You can try disabling your Firewall setting or try connecting using different Internet Service Provider.

Thanks!

While building 7 nodes hadoop cluster, cloned host in Vmvare and got exactly same machine with all the package and configuration. For building one node cluster, yum command used to build hadoop. But if we have 7 different machines given then how we will install hadoop on all machine. Do we need to run yum to install on all machines first and then continue with changing configuration. If i build new cluster with new machines then formatting and deleting of files required?
What will be the steps then if i need to build new cluster with separate linux machines???

I have setup cloudera manager on google cloud with 3 nodes. BuT I can't access NameNode and ResourceManager Web UI with hostname.
If I replace hostname with IP address then I can access. Please reply asap

Hi learner,
You can create an entry in your /etc/hosts file and map your IP address and hostname. This will help to resolve your query.
