THANK YOU SIR
your teaching style is awesome
Thanks a Lot !! for explaining the core concept
Pls bring next set of hadoop tutorials... it's very useful ...
hello sir, it there any way to upload or transfer files from my windows to the hadoop hdfs ?
Sir whats d basic difference between facl and ranger ?
@3:50 or so, I could not understand what 'chmod' couldn't do and why we have to use ACL. Must be a simple thing but I didn't get it.
Got it: If you need to setup permissions to a whole new user (of another group), then ACL would be used. Here a dir is owned by 'hdfs', but ACL is used to also have 'root' user read/execute as well.
If the files are not executables then how the map-reduce programs execute on HDFS. I understand that they use Map-reduce framework but still the files would be execuatbles and stored on HDFS.
god will give you happiness.
please i have a question can you create a tutorial for HUE (creating users with permission not to delete any data file from hue i.e tables of hive and hbase ) so that users only have the permission to execute the query and read the tables from beeswax.
You should be able to achieve it easily using Ranger. I thought of adding a video on Ranger as a next item. But focus changed to something else. Will do it sometime.
how we can get ambari software
It comes along with Hortonworks Hadoop Distribution.
What is use of setfacl -Rdm u: username:rwx foldernam
