I've installed and configured MIT Kerberos for Windows Hive ODBC connection. I could not create Kerberos ticket for more than one user, the new ticket created overwrites the existing ticket. Hence multiple user accessing that Windows machine could not obtain a valid ticket to connect to Hive ODBC connections. I've set krbs.conf from the Hive server and KRB5CCNAME is set to C:\temp\krb5cache. Please let me know how to configure this to have more valid tickets for each user.

I have 5 Data nodes, where 1 Data node crashed. Name node is still replicating the data blocks of the crashed Data node. What happens when I recover the crashed Data node. The data blocks which is under replicated will be reported but what happens to already replicated blocks. Will they be marked as corrupted blocks or will be deleted/removed since there will be 4 replicas?

I have 5 data nodes with 3*2Tb disk (6 Tb) in each data node with 3 partitions for each node, /mnt/data1, /mnt/data2 and /mnt/data3. I need to remove 1 disk (/mnt/data3) on all data nodes, how can I achieve this with minimum downtime. Current hdfs disk usage is 10 TB HDP 3.1

Hello @PabitraDas Sorry for the late reply, I tested this configuration for having 3 partitions of 2 TB space in the new nodes, like /hdp/hdfs01, /hdp/hdfs02, /hdp/hdfs03 but when I added the nodes to the cluster I saw it create directories under /hdp for other partitions as well eg., /hdp/hdfs04 - /hdp/hdfs09 like in the other old Datanodes, where /hdp is in root partition. I believe it had created these directories from HDFS configs where the DN directories are /hdp/hdfs01 - /hdp/hdfs09

@nthomas thank you for your reply. So my configuration would be: Realm Name: ABC.EXAMPLE.COM domain_realm: .example.com = EXAMPLE.COM example.com = EXAMPLE.COM this configuration will map all my hdp nodes to this Realm correct? All my hdp nodes (EST) should be in sync with Ldap server (UTC)
