Just finished getting a HDP 2.0 Alpha deployed as a single node on Centos 6.2 under VMWare and wanted to feedback.
All the packages required were found find in the standard and epel repos. All at suitable versions AFAICT.
Getting as far as the HMC service started, everything went smoothly
When deploying services to the node there were two issues I came across:
HMC seems to select devices as the starting point for folders so accepting the defaults leads to a failure. On my VM it selected /dev/mapper/vg_hd01-lv_root and /dev/mapper/vg_hd01-lv_home and attempts to create hadoop/… directories under that. Being devices, this fails. Unticking the default devices and giving a base directory in the text box allows the installation to continue.
Next up, the default java heap size for the map tasks under mapred is set to 256Mb. When deploying on a single box this leads the mapred test to fail with a java heap exception. Changing it to 2048Mb allowed the test to pass on my VM.
Both of these failures were repeatable under my VM (tested using snapshots) so I can provide logs if anyone at HortonworksHQ needs them.
Now it’s deployed, time to start playing
