Hi, We are in process of migrating from RC4 to AEC in Cloudera manager for Kerberos. Could you please help me to understand if there is any issue while changing from RC4 to AEC. Do I need to recreate the keytabs ? If yes canI force the accounts in Active directory to use AEC from RC4 ?

Hi, I have 6 disks installed on each server with 3 data nodes. I am having 3 disks of 1TB and 3 disk of 4TB. Now what is happening that the smaller disk 1 TB are getting full frequently and Impala stops working. Is there a way that I can replicate those disks with some percent of free space? Like none of the 6 disk should exceed 80% of usage until the balancer completes.
