Hello,   If the Hue Kerberos Ticket Renewer does not start, check your KDC configuration and the ticket renewal property, maxrenewlife, for the hue/<hostname> and krbtgt principals to ensure they are renewable. If not, running the following commands on the KDC will enable renewable tickets for these principals:   kadmin.local: modprinc -maxrenewlife 90day krbtgt/MY.REALM kadmin.local: modprinc -maxrenewlife 90day +allow_renewable hue/my-hostname@MY.REALM Thanks!

Hello Igor,   To create a partition in Linux, you’d need to ‘fdisk’ it first. In your example, (sdb) is the disk, so you’d need to to create the partition (sdb1): fdisk /dev/sdb After that, you’d need to format the new partition into an ext4:   mkfs.ext4 /dev/sdb1 Make sure you are mount it correctly in /etc/fstab, just like I stated in my first response, ‘mount -a’ command is a good way to examine your fstab entries. In regards to the HDFS block size, the block division in HFDS is just logically built over the physical blocks of the ext4 filesystem; HDFS blocks are large compared to disk blocks, and the reason for this is to minimize the cost of seeks. If the block is large enough, the time it takes to transfer the data from the disk can be significantly longer than the time to seek to the start of the block. If there are any additional questions, please let me know. Thanks, Laith ... View more
