Subject: Hadoop with Netapp
Hi everyone,
We are going to create a new Hadoop cluster in our company, i have to get some
advises from you:
1. Does anyone have stored whole Hadoop data not on local disks but on Netapp
or other storage system? Do we have to store datas on local disks, if so is it
because of performace issues?
<sagar>: Yes, we were using SAN LUNs for storing Hadoop data. SAN works faster
than NAS in terms of performance while writing the data to the storage. Also
SAN LUNs can be auto-mounted while booting up the system.
2. What do you think about running Hadoop nodes in virtual (VMware) servers?
<sagar>: If high speed computing is not a requirement for you then Hadoop nodes
in VM environment could be a good option, but one other slight drawback is when
the VM crashes recovery of the in-memory data would be gone. Hadoop takes care
of some amount of failover, but there is some amount of risk involved and
requires good HA building capabilities.
Thanks,
Sagar
Thanks...
