Hi Thanks for the link however my question is Read replica is performing compaction , any reason why it is so ? where should we look into to fix this issue? Since replication is done by readonly cluster it is deleting and causing FileNotFoundException

We enabled Hbase read replica - However we bump into this situtation we observed that read replica cluster is still doing compaction and Primary cluster is reporting a FileNotFound Exception for multiple regions. What could be the reason for this ? Is there any specific configuration parameter that is enabled ?

my 1st question is it possible to add Kerberos security/authentification ? Yes you can enable kerberos . my 2nd question is should i go for Kerberos or Sentry ? Sentry is for authorzation , It supports secure access to services using Kerberos. Kerberos is for authentication . Hope this helps.

is it possible to upgrade it manually? Yes it possible however , you are doing at your own risk as cloudera does not recommend usually if you are using package that its pretty straight forward , if you want to use parcel then you have to write your own custom parcel to deploy hive binaries that you want. Currenty on latest CDH 6.2. CDH 6.2 comes with Apache Hive 2.1.1 By using the above you are guaranteed that everything has been tested, bugs have been fixed, and things will roll out smoothly

What repository have you put it ? Did you chose the cloudera archive one ?

Can anyone please suggest me where should I start? Well I started it off with Apache Hadoop binary on Ubuntu Then moved on to manual installation of Cloudera hadoop finally landed in Cloudera manager . to start with I would suggest you from apache hadoop manual deployment and then side by side Cloudera Quickstart to explore other cdh eco systesm like hive , impala , many more . Do you recommend taking training courses with cloud era in order to eventually build an career in this area? That totally depends on to be frank to bring up a cluster i mean single node cluster :)) it took me a good20 days because i am from Java J2ee development guy had to roll up my sleeves to vmare , Linux Os then hang on to hadoop. Cloudera community is pretty active so we have your back on any troubleshooting :))) Welcome to the Cloudera Hadoop Community .
