Env: HDP 2.3.2 sandbox , build f1dc3df 09:23 03-0
Following link works
http://127.0.0.1:8000/about/
Following link does not work
http://127.0.0.1:8080/
It fails with time out.
*****************************************
Fix:
Power off the vm
Add new Network device
Start VM
log into the vm and run ifconfig -a
I see new device eth1 , get the IP address and then hit http://ip:8080
for example:
In my case,
[root@sandbox ~]# ifconfig -a | grep 192
inet addr:000.000.00.000 Bcast:000.000.00.000 Mask:000.000.000.0
[root@sandbox ~]#
For VMware fusion , you can follow this to add new adapter https://www.vmware.com/support/ws55/doc/ws_net_adv...

@Jesse PasswatersGood article Depending on the tool we’re using to connect, additional arguments might need to be specified. For example, to use curl, as we can see above we have to specify the --negotiate and -u arguments. The username and password we specify with -u doesn’t matter because we’re using Kerberos, so we can put whatever we want (e.g. foo:bar, or even just :). If we omit the -u then we’ll get a 401 Unauthorized error; even though its value is not actually being used.

@suresh bonam One of the best answers http://stackoverflow.com/questions/11672676/when-d... Reducers start shuffling based on a threshold of percentage of mappers that have finished. You can change the parameter to get reducers to start sooner or later. Why is starting the reducers early a good thing? Because it spreads out the data transfer from the mappers to the reducers over time, which is a good thing if your network is the bottleneck
